摘要：
Thermal decomposition of SHS-produced TiH2 powder in vacuum at temperatures below 570°C was explored by time-resolved XRD. The process got started with transformation of starting TiH2 into solid solution of hydrogen in β-Ti (β-Ti[H]) and then followed by the polymorphic β-Ti[H] → α-Ti[H] transition and subsequent hydrogen elimination to yield α-Ti. Marked changes in the phase composition of starting TiH2 were found to get started around 450°C.
