MPa, 886 MPa, 22.83% and 24.37%, respectively. The tungsten alloy is simply made up of body centered cubic tungsten phase and face centered cubic Fe3Ni2 solid solution phase. With the increase of sintering temperature, the fracture morphology of tungsten alloy is transformed from intergranular brittle fracture to transgranular brittle fracture, dimple ductile fracture, bonding phase tearing......
pattern. Fig.2(c) shows the fracture characteristics of the as-cast Mg97Zn1Y2 alloy, which can be described as a brittle quasi-cleavage mode including mainly cleavage planes from 2H-Mg phase and inter...
