Outline of Final Research Achievements |
The objective of this study was to construct a TiAl and Al alloy laminate structure by the ARB method. In the search for a prototype TiAl/Al laminate structure, a TiAl particle/Al-10%Si alloy composite was successfully fabricated at molten metal temperatures as low as 650°C. Furthermore, in this study, a new manufacturing method called the "pocket method," in which TiAl particles are packed into pockets in an Al plate, was devised. This method has been found to enable ARB processing even with brittle TiAl particles.

Academic Significance and Societal Importance of the Research Achievements |
元来、脆性であるTiAlと、高い延性をもつAlをARB加工によって接合するという新機軸を打ち出すものである。高強度や新機能を持った機能性セラミックスなどとの新規のハイブリッド材料の作製において、高温の溶湯を用いない作製方法としての応用展開が期待できる。
