摘要：
Quasistatic and dynamic tensile behavior of Zr;Al;Ni;Cu;Be;bulk amorphous alloy was investigated at the strain ratesof 10;～10;s;by using a shimadzu AG-100KNA autograph and a pneumatic tensile impact tester.It was shown that thetensile fracture strength and the fracture morphology were sensitive to the strain rate.With the increase of the strain rate,the tensile fracture strength decreased and the fracture morphology changed from cleavage into quasi-cleavage,and then intoa mixture of microvoid-coalescence dimples and quasi-cleavage veins.
