The Role of Chemical Metallurgy in the Emerging Field of Materials Science and Engineering
Y. AUSTIN CHANG
Materials science and engineering has been emerging as a unique academic discipline during the last decade and a half. The role of chemical metallurgy in this emerging field is not well defined, yet it has played an important historical role in the intellectual development of the discipline of metallurgical engineering in terms of teaching, research, and technological applications. In this lecture, I have attempted to define the role of chemical metallurgy in this emerging field and, moreover, to propose using the broader term "chemical processing of material" instead of chemical metallurgy. The role is to educate materials scientists and engineers at the baccalaureate degree level as well as the graduate degree level. I believe that if materials scientists and engineers have a good grasp of the principles of chemical processing of materials, they will be in an excellent position to tackle many of the challenging and important problems facing us in the materials field. I have also given in this lecture three diverse examples of materials problems that have been studied using the basic principles of chemical processing of materials. These examples are used to demonstrate that the tools of chemical metallurgy can be used effectively to study many contemporary materials science and engineering problems.
The Extraction and Processing Lecture was authorized in 1959 to provide an outstanding person in the field of nonferrous metallurgy as a lecturer at the annual AIME meeting. Y. Austin Chang is Wisconsin Distinguished Professor at the University of Wisconsin at Madison. After receiving his Ph.D. degree in metallurgy from the University of California at Berkeley in 1963, he spent 4 years at Aerojet-General, Sacramento, CA, working on phase equilibria and thermodynamic stability of high-temperature materials. In 1967, he joined the faculty of the College of Engineering and Applied Science at the University of Wisconsin at Milwaukee (UW-Milwaukee), and in 1980, he joined the faculty of the Department of Materials Science and Engineering at the University of Wisconsin at Madison (UW-Madison). He spent the Falls 1987 and 1991 as a Visiting Professor at Tohoku University, Sendal, Japan, and the METALLURGICAL AND MATERIALS TRANSACTIONS B
Massachusetts Institute of Technology, Cambridge, MA, respectively. He has long-standing research interests in the application of thermodynamics, phase equilibria, and kinetics to chemical/extractive metallurgy and the emerging general field of materials science and engineering. His research has led to the publication of 300 articles. In addition to pursuing an active research career, he has made important contributions to education, serving as Department Chair first at UW-Milwaukee and then at UW-Madison for a total of more than 15 years. His contribution has been recognized by numerous awards, such as the 1989 W. Hume Rothery Award, the 1990 Educator Award, and a 1991 Fellow Award a
