摘要：

Early fatigue studies on bulk metallic glasses (BMGs) have indicated fatigue strengths lower than anticipated. It was suspected that environmental effects degraded the fatigue life. In the present study a zirconium-based BMG, BMG-11 (Zr-10Al-5Ti-17.9Cu-14.6Ni, at.%), was tested in vacuum and air. This comparison was made to define any-detrimental environmental effects due to water vapor on the fatigue lifetime of BMG-11. The limited results obtained so far suggest that water vapor in air does not affect the lifetime. Moreover, the fatigue endurance limit for BMG-11 in air was found to be quite high, 907 MPa, and comparable to, or better than, those of many conventional high-strength alloys.
