    • Abstract
  • On the basis of studying the Poisson ratio given by Dyane and H.A.Kuhn,the Plastic Poisson ratio of Porous comPaCts and their exPression in connection with stress state have been Put forward.The Plastic densification formula of Porous comPacts in connection with stress state has also been deduced.Therefore,the effects of static hydraulic stress and Plastic deformation on Plastic densification can theoretically be Proved.
    Some typical technologies for the densifieation of Powder have been analyzed.The formula of densification is useful for different technologies of densification.This is of practical significance for comprehensive understanding the difference and relationship between various technologies.
