The Freshman Seminar Program has been designed to provide new students with the opportunity to explore an intellectual topic with a faculty member in a small seminar setting. The Department offers the following selections:
The Bicycle: Introduction to Engineering Materials
UNITS: 1 (Must be taken on a passed/not passed basis.)
INSTRUCTOR: Professor Thomas Devine
PREREQUISITES: None.
COURSE DESCRIPTION:
Beginning with the very first meeting, students will get their hands dirty taking apart bicycles, analyzing their designs, methods of construction and uses of materials. The basic tools of materials science and engineering will be utilized to learn about characteristics such as strength, fabricability, joinability, and resistances to fatigue, corrosion, and wear that are required of the materials selected for various components of the bicycle. Some reading outside of the classroom will be required as well as a final oral report, which describes the advantages and disadvantages of the bicycle investigated.
COURSE FORMAT: One hour of lecture per week.
The Silicon Century
UNITS: 1 (Must be taken on a passed/not passed basis.)
INSTRUCTOR: Professor Oscar D. Dubon
PREREQUISITES: None.
COURSE DESCRIPTION:
The realization of the first solid-state transistor more than fifty years ago sparked a revolution in electronics that has touched nearly all aspects of our lives. From the development of the transistor radio to the sequencing of human DNA, electronics, have played a central role in countless technological and scientific achievements during the twentieth century. At the heart of this revolution lies silicon, the material used in the fabrication of integrated circuits. We will review the events that shaped the electronics revolution, the advances in materials science that have driven the evolution of silicon-based devices, and the emergence of new materials that my enable further innovations and discoveries in the twenty-first century. We will also explore the important connection between research activities at UC Berkeley and developing technologies in Silicon Valley.
COURSE FORMAT: One hour of lecture per week.
Materials in Music
UNITS: 1 (Must be taken on a passed/not passed basis.)
INSTRUCTOR: Professor Ronald Gronsky
PREREQUISITES: None.
COURSE DESCRIPTION:
Is a rosewood fretboard any better that a maple one? Why does the same brass cymbal go from “crash” to “clunk” when aged? Can the tonal range of magnetic pick-ups be enhanced in single coil, humbucking, or triple-wound configurations? Does it really matter if those strings are nickel-wrapped? Is Platinum better? The answer to these questions lies in the microstructure of materials, as illustrated in this hands-on-seminar for musicians, poets, or engineers. We will establish the relationship between the acoustical signatures of various materials used in music and their microstructures, to show how performance (tone) can be optimized through microstructural manipulation.
COURSE FORMAT: One hour of lecture per week.
Materials and Weapons of War Through History
UNITS: 1 (Must be taken on a passed/not passed basis.)
INSTRUCTOR: Professor J. W. Morris, Jr.
PREREQUISITES: None.
COURSE DESCRIPTION:
For most of known history, advances in materials technology have appeared primarily in two areas: objects of art and weapons of war. The former build civilizations. The latter have often set its course, as critical military engagements from Kadesh to Kosovo have most often been dominated by the forces with the superior technology. In this seminar we shall use the development of weapons through history as a vehicle to understand the important properties of different types and classes of materials, and trace their technological development and technical significance across the millennia.
COURSE FORMAT: One hour of lecture per week.

UNITS: 1 (Must be taken on a passed/not passed basis.)
INSTRUCTOR: Professor Daryl Chrzan
PREREQUISITES: None.
COURSE DESCRIPTION:
The popularity of skateboarding and other extreme sports is increasing at a rapid pace. The sports are termed extreme in part because they place the participants and their equipment under extreme conditions. This seminar course will explore the extreme conditions associated with skateboarding, and how materials science has been used to evolve the original sidewalk surfers into the modern day skateboard. Topics to be discussed include the physics of skateboarding (including an analysis of the inevitable slam, pool riding, and street skating) and the implications of this physics for the design of wheels, bearings, boards and trucks.
COURSE FORMAT: One hour of lecture/discussion per week.
Course may be repeated for credit as topic varies. One hour of seminar per week per unit for 14 weeks. One and one-half hours of seminar per week per unit for 10 weeks. Two hours of seminar per week for eight weeks. Two and one-half hours of seminar per week for six weeks. Sections 1-2 to be graded on a letter-grade basis. Sections 3-4 to be graded on a passed/not passed basis. Freshman and sophomore seminars offer lower division students the opportunity to explore an intellectual topic with a faculty member and a group of peers in a small seminar setting. These seminars are offered in all campus departments; topics vary from department to department and from semester to semester. Enrollments limits are set by the faculty, but the suggested limit is 25. (F,SP) Sastry

PREREQUISITE KNOWLEDGE AND/OR SKILLS TEXTBOOK(S) AND/OR OTHER REQUIRED MATERIAL:
Required text: Porter and Easterling, Phase Transformations in Metals and Alloys, CRC Press
Supplementary texts: Books that provide additional background on topics of thermodynamics, phase diagrams, diffusion, and phase transformations are on reserve and available at the Engineering Library.
COURSE OBJECTIVES:
The overall goals of the course are to: 1) develop an understanding of why materials and microstructures undergo changes by reinforcing and significantly extending concepts introduced in chemical thermodynamics courses, 2) provide an understanding of how diffusion enables changes in the chemical distribution and microstructure of materials by discussing mechanisms and rates of diffusion and the role of driving force on diffusional processes, and 3) to formulate and discuss a variety of phase transformations and the effects of temperature and driving force on the nature of the transformation and its impact on the resulting microstructure. In summary, the tools required to understand how and why phase transformations occur, and how and why microstructures can be controlled are developed.
DESIRED COURSE OUTCOMES:
The course seeks to develop an understanding of the thermodynamic driving force for phase transformations and the role that chemical driving forces, strain energy and interfacial energy play in producing or modifying these driving forces. The course attempts to indicate the important role that the unique structure and characteristics of surfaces and interfaces can have. Diffusion processes and mechanisms are introduced, and common solutions to Fick’s laws are presented to acquaint students with the key characteristics of such solutions and to provide an understanding of spatiotemporal-scaling behavior. Limitations of the solutions are also discussed. The importance of the relationship between concentration gradients and chemical potential gradients is emphasized, with spinodal decomposition serving a key role. Diffusion and the importance of the phase diagram and underlying solution thermodynamics on diffusion processes is emphasized. A number of phase transformations are described, and treatments developed with a template framework so that students can extend the considerations of model systems to more complex cases. This is done to focus attention on fundamentals and not on the details and peculiarities of specific systems. Homogeneous and heterogeneous nucleation as well as growth processes are covered to provide an understanding of the underlying factors that dictate final microstructures.
Specific outcomes of the course are:
- Understanding of thermodynamics of single and multiple component systems, solution models, activities, etc., and their relationship to the equilibrium phase diagram.
- Ability to calculate single-component and multiple-component phase diagrams from thermodynamic data or solution models.
- An appreciation of the importance and energy characteristics of surfaces and interfaces, and their impact on equilibrium microstructures and capillarity-driven processes.

- Understanding of the fundamental mechanisms of diffusion and the importance of processing conditions, notably temperature, and microstructural features such as grain boundaries, dislocations, and surfaces on the total transport in a material.
- A deeper understanding of the role of the thermodynamic driving force for diffusion, and an alternative treatment of diffusion in terms of an appropriate gradient in potential.
- Knowledge of how driving forces of varying types and barriers due to surface energy effects interact to dictate the rate of phase transformation and microstructural change.
- An understanding of how through manipulation of temperature, driving force, and initial microstructure, a wide range of final microstructures can be produced through an appreciation of the competing processes that determine the overall path of microstructural evolution.

CONTRIBUTION OF THE COURSE TO MEETING THE PROFESSIONAL COMPONENT:
An understanding of phase equilibrium, the thermodynamic basis of phase equilibrium and phase transformations, the processes by which diffusion occurs, the properties of surfaces and interfaces, and their confluence in dictating the course of phase transformations are essential elements of a materials scientist’s educational repertoire. This course seeks to provide these essentials. The course emphasizes the interrelationships between thermodynamics, kinetics and phase transformations. An extensive and challenging set of homework assignments is designed to help the students understand and appreciate these components and their interrelationships. Use of the computer and lower-division computer skills are frequently required to solve problems in an efficient manner.

COURSE OBJECTIVES:
Many structural and functional ceramic materials are fabricated from powders with a particle size below 1 µm in size, and increasingly from powders less than 100 nm is size. The overall goals of the course are to: 1) develop an understanding of the processes used to prepare such fine powders by mechanical means or by way of chemical synthesis, 2) expose the student to the key challenges and approaches used to pack powders and to form compacts, and the difficulties of and strategies for handling submicron powders, and 3) to formulate and discuss a variety of approaches to converting fine particulates into useful controlled-density, controlled-microstructure ceramic components. In summary, the key unit processes involved in the fabrication of engineering ceramics from powders are presented. The course is also relevant to those with interest in powder processing of metals.
DESIRED COURSE OUTCOMES:
The course seeks to provide the student with a comprehensive introduction to the steps and processes that are involved in processing an engineering material from a powder. The course should provide the student with a basic understanding of the materials selection and processing condition decisions that impact the final microstructure and properties of a powder processed material.
Specific outcomes of the course are:

- An exposure to alternative methods of generating ceramic bodies such as CVD and CVI and the limitations and environmental issues associated with these methods.
- An understanding of the role of particle size and particle size distribution in developing well-packed high-density compacts through forming operations. Extension of these considerations to nonspherical powders, and mixtures of powders of differing size and/or shape as in composite fabrication.

- A basic understanding of the importance of drying and additive removal as a precursor to firing of ceramics. Factors controlling cracking and warping and strategies for effectively dealing with post-forming additive removal.
- A deeper understanding of the role of the driving force for microstructural evolution and shrinkage during sintering, and the role of the relative rates of densification and coarsening on the overall microstructure that develops.
- An appreciation of how the thermal cycle, powder particle size, atmosphere, pressure, and additives can affect the densification-coarsening competition, and can be used to drive microstructural evolution along desired paths.
- An ability to relate microstructural characteristics of fired ceramics to certain aspects of processing and materials selection, and to troubleshoot failures to produce products with desired microstructural characteristics.
