Finite Element Simulation of Micro-Imprinting in Mg-Cu-Y Amorphous Alloy
Mg-Cu-Y based metallic glasses have exhibited their superior glass forming ability, and can be cast into bulk metallic glasses (BMGs). At temperatures above the glass transition temperature, the BMGs become supercooled viscous materials that can be formed into complicated shapes or patterns in micro- or even nano-scales. This paper presents the simulated forming evolution, using a finite element simulation software DEFORM 3D, and the experimental observations for the micro-imprinting of the Mg58Cu31Y11 BMGs for making hexagonal micro-lens arrays. The results demonstrate that the imprinting is feasible and promising.
