Modeling deformation behavior of Cu-Zr-Al bulk metallic glass matrix composites

In the present work we prepared an in situ Cu(47.5)Zr(47.5)Al(5) bulk metallic glass matrix composite derived from the shape memory alloy CuZr. We use a strength model, which considers percolation and a three-microstructural-element body approach, to understand the effect of the crystalline phase on the yield stress and the fracture strain under compressive loading, respectively. The intrinsic work-hardenability due to the martensitic transformation of the crystalline phase causes significant work hardening also of the composite material.
