Abstract: | A study has been made on the effects of loading scheme and conditions restricting macroscopic strain on the work-hardening
kinetics and strain accumulation in the solid state in sintering materials with bimodal pore size distributions. Active loading
intensifies the reduction in the small pores. The greatest effect comes from combining sintering with hydrostatic compression.
At the same time, kinematic constraints (partial or complete adhesion in surfaces) substantially retards the shrinkage of
large pores, which means that the porous structure can be controlled.
