Irreversible deformation of a sintered porous body of a work-hardening plastic metal II. Experimental part

Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    An analysis is made of various methods of calculating compressibility curves for porous bodies sintered from plastic metal powders. It is shown that the best approximation to experimental results is given by the method based on the use of rms viscous stresses and strains and on allowance for strain strengthening and macrodefectiveness of structure.

  2. 2.

    Taking into account the nonuniformity of strain due to density variations in compacts enables calculated results to be brought closer to experimental data obtained at low pressures.
