APDIC Japan


Japanese Committee for Alloy Phase Diagrams, Japan

The Japanese Committee for Alloy Phase Diagrams (JCPD) was founded in 1986, and now it is chaired by Professor H. Ohtani of Tohoku University. Currently, it consists of 80 members from both academia and industries, who are actively participating.

The aim of this committee is to enhance the fundamental knowledge of phase diagrams and phase equilibria of alloys, ceramics, and other materials and to seek for efficient utilization of phase diagrams as a road-map for innovative materials’ design and development. A particular emphasis of the committee has been placed on the collaborations between academia and industries through the annual meetings held twice every year. The JCPD maintains many high-level activities, and two honorable committee members, Nippon Steel Company and JFE Steel Corporation received the APDIC Industrial Award in the years 2003 and 2004, respectively, and in 2005 the Tohoku University group received the APDIC Best Paper Award. In the year 2003, the JCPD hosted the first APDIC World Round Robin Seminar (WRRS) held in Sapporo, sent lectures to the second WRRS 2006 in Rio de Janeiro and organized the CALPHAD XLV in Awaji, Hyogo pref. in 2016. More recently, the APDIC Industrial Award in 2018 was sent to the Toyota Motor Company, Toyota Central R&D Labs., Inc.

Recently, the new direction of the application of phase diagram studies has been actively explored by the members by combining CALPHAD-type approaches, first principles calculations, and kinetics simulations such as Phase Field Method. Thereby, the JCPD has been contributing to the world-wide collaborations of alloy phase diagram activities with other APDIC members.
