摘要：

The tensile properties and fatigue lives of a bulk Cu0.5NiAlCoCrFeSi glassy alloy were measured in 288 degrees C water and compared with those obtained in air at similar to 25 degrees C. The bulk glassy alloy retained good tensile properties in 288 degrees C water, i.e., tensile fracture strength and tensile fracture elongation were, respectively, 2660 MPa and 2.01% in air and a little lower, 2000 MPa and 1.49%, in 288 degrees C water. The results of fatigue tests confirmed the significant decrease in fatigue life in high-temperature water. A decrease in strain rate from 0.5 to 0.001% s(-1) decreased fatigue life by a factor of similar to 5. (c) 2005 American Institute of Physics.
