摘要: Abstract The uniaxial compressive fracture behavior of Ni 42 Cu 5 Ti 19 Zr 22.5 Al 8 Si 3.5 bulk metallic glass (BMG) was investigated. It found that the 2 mm rod exhibited a high strength 2851 MPa and plastic strain 0.5%, while 3 mm sample showed 2724 MPa nearly zero strain. property difference in two samples explained due to different structure caused by cooling rates formation. surfaces deformed consisted flat shear zone coarse zone. angles between stress axis plane changed from
