“…For a range of microelectromechanical applications (1,(7)(8)(9)(10)(11)(12), the damage tolerance and crack resistance of MGs from thermal and mechanical stress or strain cycling under partial or complete constraint is of significant scientific and technological interest (13)(14)(15)(16)(17)(18). Bulk MGs can undergo fully reversible elastic deformation to a strain limit of about 2%, more than an order of magnitude greater than that of coarse-grained crystalline metals, whereupon inelastic deformation commences at stress levels on the order of gigapascals (1,2).…”

“…However multiple fatigue studies for the Zr-based family have been reported, and depending on the composition, loading geometry, and loading frequency, endurance limits ranging between 5% and 25% of the associated yield strengths have been reported. 13,14 Therefore, the endurance limit of the metallicglass foam material investigated in this study appears to fall within a range representative of the fatigue-endurance limit of the parent metallic glass. By plotting the fatigue ratio versus fatigue life for the ten foam specimens, a universal stress-life curve for the foam can be constructed.…”

“…As seen in the curve, the average fatigue life of the material increases with decreasing fatigue ratio until an endurance limit is attained, a trend consistent with stress-life curves of monolithic metallic glasses or other materials in general. 13,14 …”

“…Bulk metallic glasses (BMGs) are known for their excellent properties including high fracture strength, high hardness, large elastic deflection (Chen, 2008;Lewandowski, 2001;Trexler and Thadhani, 2010;Wang et al, 2009;Gu et al, 2010;Wang, 2012). However, at temperatures well below the glass transition and at high stresses, BMGs undergo inhomogeneous deformation by concentrating severe plastic strain into nanoscale shear bands (Jiang et al, 2008a;Lewandowski and Greer, 2006;Yang et al, 2005;Dai et al, 2005;Greer et al, 2013;Spaepen, 1977;Argon, 1979;Yang et al, 2006;Xu and Ma, 2014).…”
