Abstract

High-cycle fatigue (HCF) experiments were conducted on zirconium (Zr) -based bulk-metallic glasses (BMGs): Zr₅₀Al₁₀Cu ₄₀ and Zr₅₀Al₁₀Cu₃₀Ni₁₀, in atomic percent. The HCF tests were performed using an electrohydraulic machine at a frequency of 10 Hz, with a R ratio of 0.1, and under tension-tension loading. Note that R=σ_min/σ _max., where σ_min and σ_max are the applied minimum and maximum stresses, respectively. The test environments were air and vacuum. A high-speed and high-sensitivity thermographic infrared (IR) imaging system has been used for nondestructive evaluation of temperature evolution during fatigue testing of BMGs. Limited temperature evolution was observed during fatigue. However, a sparking phenomenon was observed at the final fracture moment of Zr₅₀Al₁₀Cu₃₀Ni ₁₀. The effect of chemical composition on the fatigue behavior of the Zr-based BMGs was studied. The fatigue-endurance limit of Zr ₅₀Al₁₀Cu₃₀Ni₁₀ (865 MPa) is somewhat greater than that of Zr₅₀Al₁₀Cu₄₀ (752 MPa) in air. The fatigue-endurance limits of these two BMGs were comparable to those of ductile crystalline alloys. The fatigue lives in vacuum and air were generally found to be comparable. The vein pattern and droplets with a melted appearance were observed in the apparent melting region. There are microcracks on the outer surface of the specimen, which could be associated with multiple fatigue crack-initiation sites. These microcracks might result from shear bands and shear-off steps.
