Abstract

Zr_41.2Ti_13.8Cu_12.5 Ni₁₀Be_22.5 bulk amorphous alloy was prepared by arc-melting and rapid casting into a copper mould. Hydrogen charging was performed electrochemically in glycerine-phosphoric acid electrolyte. It is shown that hydrogen increases the thermal expansion coefficient at glass translation temperature and decreases the thermal expansion coefficient at crystallization temperature. The relaxation process from amorphous to a more regular structure is delayed by hydrogen charging. In addition, the average first-neighbour distance and the depth of effective pair potential can be increased after hydrogen charging.
