摘要：

Tensile deformation behavior of a Zr55Al10Cu30Ni5 bulk metallic glass at 700 K (in the supercooled liquid region) was investigated at strain rates ranging from 3 x 10(-3) to 3 x 10(-2) s(-1). The material exhibited excellent mechanical formability with a maximum elongation of similar to800%. Structures of the material, both before and after deformation, were examined.
