The Volume was prepared under the direction of the ASM International Alloy Phase Diagram and the Handbook Committees. Foreword Phase diagrams thermodynamic data in graphical form are one of the basic tools of the metallurgist materials scientist and materials engineer. They can be used for alloy design selection of hot-working and fabricating parameters prediction of performance guidance in selection of hot-working and fabricating parameters prediction of performance guidance in selection of heat-treating process parameters solving performance problems including failure analysis and for many other purposes. The formation of The American Society of Steel Treating the forerunner of ASM International was based on better understanding of heat-treating technology this understanding was of course rooted in part in the proper utilization of phase diagrams. Experimental tools such as metallography were used in those early days both to determine phase diagrams and to link the heat-treating process with the desired microstructure. In 1978 ASM International joined with the National Bureau of Standards now the National Institute of Standards of Technology or NIST in an effort to improve the reliability of phase diagrams by evaluating the existing data on a system-by-system basis. ASM raised 4 million from industry and government sources and NIST provided a similar amount of financial and in-kind support for this historic undertaking. An international effort was mounted simultaneously with similar objectives. As a result all of the important binary systems have been evaluated and international partners have evaluated more than 2000 ternary systems. ASM actively participates in the Alloy Phase Diagram International Commission APDIC which comprises cooperative national or .
