Test Size And Volume Effects On Fatigue Behavior Of Bulk Metallic Glasses (Bmgs), Qingming Feng
Masters Theses
As a potential structural material, performance of bulk metallic glasses (BMGs) under cyclic loading is critical in applications. Among the mechanical properties of metallic glasses, the fatigue behavior received less attention and is not well understood. BMGs exhibit significant size effects on the mechanical behavior under monotonic loading, such as compression, tension, and bending. At the same time, different test-volume could lead to a distinct difference in the mechanical behavior of BMGs.
The fatigue behavior of the Zr52.5Cu17.9Ni14.6Al10.0Ti5.0 [atomic percent (at. %)] BMG alloy (Vitreloy 105) with different sizes has been …
