摘要

High-cycle fatigue (HCF) experiments in air and vacuum at room temperature were conducted on zirconium (Zr)-based bulk-metallic glasses (BMGs): Zr_(50)Cu_(40)Al_(10), Zr_(50)Cu_(30)Al_(10)Ni_(10), and Zr_(50)Cu_(37)Al_(10)Pd_3 in atomic percent. The fatigue-endurance limit of Zr_(50)Cu_(37)Al_(10)Pd_3 was found to be significantly greater than those of Zi_(50)Cu_(40)Al_(10) and Zr_(50)Cu_(30)Al_(10)Ni_(10), which indicates that the inclusions of Pd and the resulting nano structures improve the fatigue resistances of the Zr-based BMGs. The fatigue lives in vacuum and air were generally found to be comparable.
