Abstract

High-cycle fatigue (HCF) experiments in air and vacuum at room temperature were conducted on zirconium (Zr)-based bulk-metallic glasses (BMGs): Zr50Cu40Al10, Zr50Cu30Al10Ni10, and Zr50Cu37Al10Pd3 in atomic percent. The fatigue-endurance limit of Zr50Cu37Al10Pd3 was found to be significantly greater than those of Zr50Cu40Al10 and Zr50Cu30Al10Ni10, 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.
