Research results on the viscous flow deform.tion behavior of bulk am.rphous alloy in different system. are reviewed. The m.terial exhibits an ideal Newtonian fluid at a high tem.erature. Analytical solution of lam.llar fluid flow behavior is used to discuss the viscous flow behavior of the bulk am.rphous alloy in the supercooled liquid state. A m.terial m.del, which describes such deform.tion behavior of m.6oCusoYlo am.rphous alloy, is introduced into the finite elem.nt m.thod of m.croform.n8 process. surface feature size was investigated and found not sensitive to the m.cro form.bility. Bulk am.rphous alloy m.y possibly be applied to m.croelectro-m.chanical-system. （m.m.） fabrication.
