块体非晶合金具有优异的强度和断裂韧性，在工程结构中具有潜在的应用价值。它们的抗疲劳性对于应用也非常重要。研究了Zr 61 Ti 2Cu 25 Al 12大块非晶合金的拉-拉疲劳损伤行为。Zr 61 Ti 2Cu 25 Al 12玻璃的拉-拉疲劳极限为195 MPa，高于高韧性钢。试样的断裂形态取决于所施加的应力幅值。在疲劳试验中，发现玻璃表面出现了垂直于加载方向的剪切带，其应力幅高于玻璃的疲劳极限。玻璃的疲劳裂纹是由剪切带群中的剪切带引起的。我们的工作表明，Zr 61 Ti 2Cu 25 Al 12玻璃是一种有竞争力的结构材料，并揭示了提高块体金属玻璃的抗疲劳性能。
Bulk metallic glasses have application potential in engineering structures due to their exceptional strength and fracture toughness. Their fatigue resistance is very important for the application as well. We report the tension-tension fatigue damage behavior of a Zr61Ti2Cu25Al12 bulk metallic glass, which has the highest fracture toughness among BMGs. The Zr61Ti2Cu25Al12 glass exhibits a tension-tension fatigue endurance limit of 195 MPa, which is higher than that of high-toughness steels. The fracture morphology of the specimens depends on the applied stress amplitude. We found flocks of shear bands, which were perpendicular to the loading direction, on the surface of the fatigue test specimens with stress amplitude higher than the fatigue limit of the glass. The fatigue cracking of the glass initiated from a shear band in a shear band flock. Our work demonstrated that the Zr61Ti2Cu25Al12 glass is a competitive structural material and shed light on improving the fatigue resistance of bulk metallic glasses.
