چکیده انگلیسی
The fatigue behavior of Cu47.5Zr48Al4Co0.5 bulk metallic glass composite (BMGC) containing B2 phase was investigated under uniaxial compression-compression loading modes at 80Â Hz with a 0.1Â R ratio. The Cu46.5Zr46.5Al7 bulk metallic glass (BMG) was selected as a reference materials. It was found that the BMGC exhibits a lower fatigue limit (1300Â MPa) than that of its reference BMG (1500Â MPa), which is due to the lower yield strength of the BMGC. The fatigue limit is characterized by the stress range, Ïr=(Ïmax-Ïmin), where Ïmin and Ïmax are the applied minimum and maximum stresses, respectively. However, the fatigue ratio (the maximum stress range/yield strength) of the BMGC is higher than that of the BMG, because the “blocking effect” and “martensitic transformation effect” of B2 phase can effectively impede the propagation of fatigue crack and enhance the yield strength of the BMGC. Briefly, B2 phases can obviously improve the fatigue ratio of the CuZr-based BMGCs and thus improve its fatigue behavior, though it can not improve its fatigue limit.
