-Mg-Cu alloy is a favorable choice for aerospace applications requiring good combination of strength and toughness, which is greatly influenced by the coarse intermetallic particles. The evolution of intermetallic particles in an Al-Zn-Mg-Cu alloy during heat treatment was studied by field emission gun scanning electron microscopy (FEG-SEM) and X-ray diffractometry(XRD). The results show......
℃). Then contact stress between the intermetallic alloy and SiC wear particles induces martensitic transformation (B2 TiNi phase→B19′ phase). Good pseudoelasticity of B2 TiNi phase plays an active role... wear mechanism of the intermetallic alloy and high-chromium cast iron under abrasive wear test is micro-cutting and plowing by hard SiC wear particles. 3) Combination of hard Ti2Ni and ductile TiNi......
