Abstract

High-cycle fatigue (HCF) experiments were conducted on zirconium (Zr)-based bulk-metallic glasses (BMGs). The test environments were in air at room temperature. The fatigue-endurance limit of Zr50Cu 30Al10Ni10 (865 MPa) is somewhat greater than those of Zr50Cu40Al10 (752 MPa) and Zr 41.2Ti13.8Ni10Cu12.5Be 22.5 (Batch 59: 703 MPa and Batch 94: 615 MPa). The fracture morphology indicates that fatigue cracks initiate from shear bands or some defects. The J spacing was measured in the crack-propagation region of the fatigue-fractured surface. Its relationship with the stress-intensity-factor range was developed, which is different from the empirical relationship for crystalline alloys.
