摘要：

The effects of non-Newtonian plastic deformation of a Cu-based amorphous alloy (Cu50Zr50)(92)Al-8 in the super cooled liquid region on the isothermal crystallization behavior and mechanical properties of the amorphous alloy were investigated. The results showed that the non-Newtonian deformation could promote the isothermal crystallization process of the alloy, and the main isothermal crystallization products were the CuZr phase with a cubic structure (B-2 phase) and its Martensitic phase. The alloy after the non-Newtonian deformation and the isothermal annealing exhibited a yielding point at the initial stage of deformation on its compression stress-strain curve, which may be caused by the stress induced martensite transformation.
