Abstract

In this paper, the mechanical and physical properties of a Ti-47Al-4(Nb, W, B) alloy (CTI-8) developed by Chrysalis Technologies are presented. The properties of CTI-8 alloy are compared with other TiAl-base alloys and currently used materials for high temperature applications. The CTI-8 alloy exhibits excellent creep resistance, good high temperature strength and better physical properties than the currently used materials. The comparisons suggest that CTI-8 has a great potential in aerospace and automotive industries.
