Automotive Application of Advanced Superalloys

Masashi Yoritaka; Yukio Yamamoto; Yasuaki Hasegawa; Tomio Hokari

Based on the testing reported here, a new Ni-based superalloy has been adopted for use in Mazda RX-7 heat-resistant turbochargers. The new alloy exhibits a high temperature stability of the γ phase, resisting the initial stage of creep rupture. Casting parameters and chemistries are varied to produce a directionally solidified columnar structure, which eliminates internal grain boundary rupture sites. The Mazda super-high temperature turbocharger was used to achieve a world speed record (GT-C class) of 238.442 mph at Bonneville, Utah, last August.
