摘要：
The hydride cycle process was successfully applied to synthesize single-phase α2-Ti3Al, γ-TiAl, and TiAl 3 aluminides. The formation of aluminides was found to proceed by solid-state reaction mechanism, without melting. The process takes advantage of its relatively low temperatures (600-1000°C), short duration (2-3 h) of a single-step synthetic procedure, and lower energy requirements. © 2014 Allerton Press, Inc.
