Abstract

Abstract

The deformation and densification law of powder forging was studied for Fe-based sintered porous material.The local strain limit criterion for the cracking on surface was achieved,and the process parameters of forming limit were obtained for the cracking limitation based on experimental results of powder forging for Fe-based porous material with different initial conditions,which include friction factor,relative height and relative density.With the experimental results,the design of mould and green compact of sintered porous material can be optimized.
- powder forging,
- upsetting,
