Abstract

Abstract:

The extrusion forming process of a rapidly solidified/powder metallurgy (RS/PM) damping aluminum alloy,FMS0714/10(Zn-30Al),is studied using the finite element software ANSYS.The effects of friction coefficient and extrusion ratio on the forming process are investigated in a wide parametric variation region,f,0-0.2; λ,2.78-8.65.

Key words: damping , aluminum , alloy, , forming , process, , extrusion, , surface , flaw, , numerical , simulation, , finite , element , method
