Publication Information and Contributors

Alloy Phase Diagrams was published in 1992 as Volume 3 of the ASM Handbook. 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 regional committees in 13 countries. APDIC was formed "to set overall objectives, determine priorities for

alloy systems to be assessed, coordinate the assessment programs of APDIC members and associate members, establish

scope and quality standards for assessment programs in other countries, and assist in the timely dissemination of the

resultant phase diagram data."

The complete results of the international effort are recorded in various periodical and reference publications. However,

we have continued to hear from ASM members that a summary version consisting primarily of phase diagrams should be

published as an ASM Handbook for the practicing engineer. While such a Handbook could not contain all the diagrams

and data, careful selection would ensure the inclusion of the most important systems, with references to other more

complete sources. The present Handbook is the result of our attempts to meet these criteria and the stated need.

No reference book of this nature could be published without the contributions of literally hundreds of technical and staff

workers. On behalf of ASM International, we extend our sincere thanks and appreciation to the category editors,

contributors, reviewers, and staff who worked in this international effort. Thanks are also due to the ASM Alloy Phase

Diagram and Handbook Committees for their guidance and support of the project.

Preface

Alloy phase diagrams have long been used successfully by the scientific, engineering, and industrial communities as

"road maps" to solve a variety of practical problems. It is, thus, not surprising that such diagrams have always been an

important part of ASM Handbooks. The previous ASM compilation of commercially important diagrams appeared in

Volume 8 of the 8th Edition of Metals Handbook.

Shortly after publication of the earlier volume in 1973, recognition of the universal importance of alloy phase diagrams

led to the formation of several national phase diagram programs, as well as the International Programme for Alloy Phase

Diagrams to act as the coordinating body for these activities. In the U. S., the national program has been spearheaded

jointly by ASM International and the National Institute of Standards and Technology.

To meet the pressing need for diagrams, the national programs and the entire International Programme had two main

goals: to increase the availability of phase diagrams and to ensure that the diagrams made available were of the highest

possible quality. The specific tasks that were undertaken to accomplish these goals included assembling all existing data

related to alloy phase diagrams, critically evaluating these data, using the data to construct the most up-to-date and

accurate diagrams possible, and making the resulting diagrams readily available for use.

With the publication of the three-volume set of Binary Alloy Phase Diagrams, Second Edition, by ASM in 1991, the

binary alloy portion of this monumental task is virtually complete. In addition, the first-ever truly comprehensive

collection of ternary diagrams, the multivolume Handbook of Ternary Alloy Phase Diagrams, is scheduled for publication

by ASM in 1994. Information from these two extensive and current diagram sources have been used as the basis of this

updated engineering reference book, which reproduces the diagrams of the most commercially important systems (1046

binaries plus 80 ternaries) in a single, convenient volume. These alloy systems are represented by more than 1100 binary

diagrams and 313 ternary diagrams, all plotted in weight percent as the primary scale.

The binary diagrams reproduced in this Handbook were selected from the 2965 systems covered in Binary Alloy Phase

Diagrams, with updated diagrams from literature published since January 1991. Included with the binary diagrams is a

complete index of all known alloy phase diagrams from all sources, listing where each can be found should a problem

arise concerning a binary system not covered in this Handbook. Although many of the diagrams listed in this index (and a

few of those reproduced in this volume) have not been evaluated under the Programmed, they were selected to represent

the best available. Updated binary diagrams from the phase diagram update section of the Journal of Phase Equilibria and

abstracts of new full-length evaluation from the Journal of Phase Equilibria and the Monograph Series on Alloy Phase

Diagrams are available from ASM International on a continuing basis through the Binary Alloy Phase Diagrams Updating

Service.

The ternary diagrams reproduced here were selected from more than 12,000 diagrams being assembled for the ternary

handbook. Where available, diagrams from recently published evaluated compilations were selected. The remainder were

selected to represent the best available.

To aid in the full and effective use of these diagrams to solve practical problems, we have included an Introduction to

Alloy Phase Diagrams, which contains sections on the theory and use of phase diagrams, and an Appendix listing the

relevant properties of the elements and their crystal structures.

While the work of developing additional data, expanding alloy system coverage, and refining existing diagrams must and

will continue, the quality checks built into the programme ensure that the diagrams reproduced here are as accurate and

reliable as possible. Credit for this belongs to the conscientious work of all the experts involved in the worldwide

Programme, especially Prof. Thaddeus B. Massalski and Dr. Alan A. Prince, who coordinated the evaluation efforts

during the period of greatest activity.
