The compressive mechanical behavior and fracture process of Zr_52.5 Cu_17.9Ni_14.6 Al10 Ti5 bulky amorphous alloy were investigated in detail at a strain rate of 10-4s-1. The compressive fracture strength, elastic deformation and elastic modulus of the alloy are 1770MPa, 2.1% and 82GPa, respectively. From SEM observation of fracture surface, the fracture process of bulky amorphous alloy can be described as a tearing process along shear bands. The increase of temperature in the local region was calculated roughly.
