Abstract

Abstract:

Research results on the viscous flow deformation behavior of bulk amorphous alloy in different systems are reviewed. The material exhibits an ideal Newtonian fluid at a high temperature. Analytical solution of lamellar fluid flow behavior is used to discuss the viscous flow behavior of the bulk amorphous alloy in the supercooled liquid state. A material model, which describes such deformation behavior of Mg₆₀Cu₃₀Y₁₀ amorphous alloy, is introduced into the finite element method of microforming process. Surface feature size was investigated and found not sensitive to the micro formability. Bulk amorphous alloy may possibly be applied to micro-electro-mechanical-systems (MEMS) fabrication.

Key words: Bulk amorphous alloy, Supercooled liquid state, Micro formability, Lamellar fluid flow
