Trends of composite casting technology and joining technology for castings in Japan

State of technologies in Japan related to composite casting was reviewed based on the three year survey of Composite Casting Process Sub-Committee in Committee on Foundry Technology (24th) of JSPS. Other than making metal matrix composite, cast-in insertion, bonding and joining of cast materials and other technologies combining different materials by casting process were included. Basic theories and the key technologies are explained, and a number of typical examples of products, on production or on experimental bases, were reported. Overseas literatures were also surveyed.
