Paper Title:
Research and Simulation of Influence of Different Pressing Velocity on Powder Metallurgic Products Properties
  Abstract

The warm compaction process is simulated by the finite element analysis software which is MSC/MARC. The thermal mechanically coupled analysis method is applied based on the updated Lagrangian Method to simulate powder warm compaction process under different frictional condition and different strain rate. The influence of different friction condition and strain rate is researched on the density and the mechanics behavior of powder green. The results indicate that for cylindrical powder metallurgic products, with the increasing of pressing velocity (namely strain rate), work hardening of powder is gradually evident, and leads to larger distribution grads of density and equivalent stress of green. The improvement of friction condition is propitious to reduce the disadvantage of work hardening and improve the uniformity of distribution of density.
