CCT Diagram Database (CCTD)
The welding database system to predict hardness and microstructural constituents in the heat affected zone and to determine optimum welding conditions has been developed by using an estimated thermal cycle and the database of CCT diagram for welding.
Welding Database was supported by Database Development Program in Japan Science and Technology Agency (JST). The database is built by collaboration with National Institute for Materials Science and JST.
