Solubility and diffusion of hydrogen in amorphous CuTi alloys

Abstract

Amorphous alloys of the CuTi binary system were prepared by a rapid quenching method and their characteristics such as crystallization temperature, electrical resistivity, density and Vickers' hardness were measured. The diffusion of hydrogen in two groups of specimens, i.e. amorphous CuTi alloys and the crystalline TiH 2Cu phase produced by the decomposition of the CuTiH system, was investigated using the evolution method. The results showed that the activation energy for the evolution of hydrogen was dependent on the composition of the binary CuTi alloys.
