Solidification, Segregation, and Banding in Carbon and Alloy Steels
GEORGE KRAUSS
STEELS are defined, first and foremost, by their chemistry. For the steel products of interest in this article, steels are defined as alloys of iron, and small amounts of carbon
and other chemical elements. In particular, carbon steels are defined as alloys with a maximum of 1.65 wt pct Mn, a maximum of 0.60 wt pct Si, and a maximum of 0.60 wt pct Cu. Maxima in S and P are also specified, but no minimum content of other elements is listed.[1] Alloy steels are steels
Dr. George Krauss is currently University Emeritus Professor at the Colorado School of Mines and a metallurgical consultant specializing in steel microstructural systems. He received the B.S. in Metallurgical Engineering from Lehigh University in 1955 and the M.S. and Sc.D. degrees in Metallurgy from the Massachusetts Institute of Technology in 1958 and 1961, respectively, after working at the Superior Tube Compnay as a Development Engineer in 1956. In 1962–63, he was an NSF Postdoctoral Fellow of the Max Planck Institut für Eisenforschung in Düsseldorf, Germany. He served at Lehigh University as Assistant Professor, Associate Professor, and Professor of Metallurgy and Materials Science from 1963 to 1975, and in 1975, joined the faculty of the Colorado School of Mines as the AMAX Foundation Professor in Physical Metallurgy. He was the John Henry Moore Professor of Metallurgical and Materials Engineering at the time of his retirement from the Colorado School of Mines in 1997. In 1984, Dr. Krauss was a principal in the establishment of the Advanced Steel Processing and Products Research Center, an NSF Industry –University cooperative research center at the Colorado School of Mines, and served as its first Director until 1993. He has authored the book Steels: Heat Treatment and Processing Principles, ASM International,
1990, coauthored the book, Tool Steels, Fifth Edition, ASM International, 1998, and edited or coedited conference volumes on tempering of steel, carburizing, zinc-based coatings on steel, and microalloyed forging steels. He has published over 300 papers and lectured widely in technical conferences, universities, corporations, and ASM International Chapters, including a number of keynote, invited, and honorary lectures. He presented the Edward DeMille Campbell Memorial Lecture of ASM International in 2000. Dr. Krauss has served as the President of the International Federation of Heat Treatment and Surface Engineering (IFHTSE), 1989–91, and as President of ASM International, 1996-97. He is Fellow of ASM International, TMS, and IFHTSE. He has been awarded the Adolf Martens Medal of the German Society for Heat Treatment and Materials, the Charles S. Barrett Silver Medal of the Rocky Mountain Chapter of ASM, the George Brown Gold Medal of the Colorado School of Mines, and several other professional and teaching awards, including the ASM Albert East
