Structure-Mechanical Properties Correlation in a Hydrogenated Ti-Based In-Situ Amorphous Matrix Composite

摘要

Ti_(50)Zr_(25)Cu_(25) in-situ composite ribbons consisting of metastable β-Ti crystalline phase in an amorphous matrix was studied for its structural stability and mechanical properties after hydrogenation. On annealing, dissolution of the metastable β-Ti phase occurred. On hydrogenation, upto ～60 at.% hydrogen was obtained and hydrogen-induced amorphization occurred. The fracture strength of the hydrogenated composite indicated that it was mechanically stable even for high hydrogen contents.
