The effect of compressing stresses on deformation and contact phenomena in fibrous pressed materials in sintering

摘要

The control possibility of deformation and contact phenomena in porous fibrous materials of metal is studied. It is determined that sintering of fibrous materials in conditions of small compressing stresses in direction of pressing allows completely to depress the volume growth of material observed as pressing aftereffect on initial stages of sintering. The materials received to such ways have considerably more the high level of physical and mechanical properties due to restoration of interpartical contacts. Ultimate strength of the specimens is in 1.5-2 times as large in comparison with control ones with the same porosity.
