Abstract: High temperature forming processes of alumina powder compacts were analyzed by using constitutive equations which are capable of predicting densification and grain growth under diffusional creep ...

Abstract: Densification and grain growth of alumina powder compacts were investigated under pressureless sintering, sinter forging, and hot pressing. A set of constitutive equations by Kwon et al. was ...

Abstract: Elastic-plastic strain hardening responses of sintered porous iron are investigated. By using the yield function of Kim, two sets of constitutive equations are obtained from the constitutive ...

Abstract: Elastic-plastic responses of porous iron under uniaxial strain cycling between two fixed values of strain are investigated. A special set of constitutive equations is formulated by including ...

Abstract: Densification behavior of 316L stainless-steel powder under die pressing was studied. The friction effects between the powder and the die wall under different die pressing modes were also ...
