摘要：

1. 1) The protective alumina-forming Al-Ti-Cr alloys identified by Perkins et al. [2] are based primarily on the τ (L12) and TiCrAl laves phases. 2. 2) The τ phase in the multiphase protective alumina-forming Al-Ti-Cr alloys is not stable at 1073K and decomposes to r-Al2Ti and Cr2Al. 3. 3) Future coating alloy development in the Al-Ti-Cr system should focus on the γ/TiCrAl laves two phase field. © 1995.
