摘要：

Bulk Cu52.5Ti30Zr11.5Ni6 and Cu53.1Ti31.4Zr9.5Ni6 amorphous alloys exhibit high fracture strength sigma(c,f) (2212 MPa and 2184 MPa. respectively), and high compressive fracture elongation epsilon(c,f) (2.1% and 2.2%, respectively). Three different vein patterns can be observed on the fracture surfaces of the samples. The high compressive fracture strength is contributed to the fracture propagation along two different directions and the formation of elongated and striated vein patterns for the tested Cu-based bulk amorphous alloys.
