The Alloy Phase Diagram International Commission

APDIC is a council of members who maintain major phase diagram activities.  It is a non-profit organization, operating worldwide.  Most of the members are professional societies represented by the chair and vice chair of their phase diagram committees. 

APDIC members are working together to exchange information and minimize duplication of effort and provide top quality databases and phase diagram information.  To provide the community with guidelines for the critical evaluation of phase diagram and thermodynamic data the members of APDIC evaluated a series of publications for recommended practice.  The publications that are considered to be broadly useful for critical evaluations can be openly accessed. 

In addition, the members work on promoting the generation, development and sharing of information on the understanding of the equilibrium state of material systems, using the most adequate techniques available.  As part of its regular activities to that objective, APDIC presents an annual Best Paper Award and Industrial Award and co-organizes every couple of years a World Round Robin Seminar dedicated to the dissemination of knowledge on the most advanced tools for understanding and applying information on phase equilibrium in materials.

History

APDIC was established in 1986 under a Memorandum of Understanding, in Orlando, Florida, primarily by the leadership of ASM international and IoM3, as an organization to promote and coordinate the assessment of phase diagrams.  Originally consisting of 10 member organizations, the commission has grown to include 18 members representing 26 countries from North and South America, Europe and Asia. More than 70 volumes on binary and ternary alloy systems totaling over 50,000 pages have been published by the members of APDIC.

Mission

To meet the needs of the world wide technical community, the APDIC members agreed to:

• Promote quality standards for phase diagram evaluations
• Assist effective dissemination of data arising
• Promote the application of phase diagrams in industry and academia
• Advance evaluation and assessment programs world wide
• Promote educational activities in the field of materials constitution and phase diagrams
