CALCULATION OF PRESSURE AND DENSIFICATION ROR POWDER FORGING

Hua Lin,Mao Hua Jie (Wuhan Automotive Polytechnic Vniversity ,Wuhan?430070,China)  
The calculation formulae of deformation pressure,workpiece density and sizes for upsetting,repressing,and closed die forging are derived based on the generalized plasticity theory of sintered powder materials.The densification effects of upsetting and repressing are compared,and a technology design principle for closed die forging is suggested .
