The new 2016 edition of ASM Handbook, Volume 3: Alloy Phase Diagrams is a revision of the original 1992 edition. 40% of the volume has been updated and now includes 1083 binary systems, 1095 binary diagrams, 115 ternary systems, and 406 ternary diagrams. The revised volume provides a more complete explanation of phase diagrams and their significance with the addition of new material on solid solutions and phase transformations; thermodynamics; isomorphous, eutectic, peritectic, and monotectic alloy systems; solid-state transformations; and intermediate phases. Users of this volume will gain a better understanding of phase diagram construction and alloy system interactions while having a valuable resource to aid in their research and engineering pursuits. Since the 1992 edition of this volume was published, improvements in experimental techniques have increased the accuracy of results, filling the remaining gaps of existing systems. Increasingly sophisticated computer modeling methods determine phase equilibria that could not be determined experimentally in a practical manner - resulting in numerous revisions of previously accepted phase diagrams, and predicted phase diagrams for newly assessed systems.
