CONCERNING THE EFFECT OF COMPRESSIVE STRESSES ON SHRINKAGE IN SINTERING OF POROUS BODIES

Abstract

Results are presented of a study of the effect of uneven compressive stresses on volume shrinkage of sintered bodies consisting of silver, copper and nickel powders (at 600 to 800 C and for 5 min.). The dependence of the shrinkage on the stress, allowing for the geometrical factor, proved to be nonlinear in the case of annealed powders, which is due to plastic deformation arising on application of the load to the sintered body. The inference may be drawn that, under conditions of free sintering, the processes occurring are diffusion processes and not plastic strain. (Author)
