Abstract
The effect on the anisotropy of linear shrinkage al.s for sintered carbide-steels of such factors as the method of forming, compaction pressure, ratio of linear dimensions, production method, and alloy composition is studied. It is estabished that an increase in the linear dimensions leads to an increase in the shrinkagae effect in the axial direction and a reduction in the radial direction. Anisotropy is at a minimum with H/D=1. Compaction in hydrostatic equipment and an increase in compaction pressure to 500 MPa markedly reduce al.s.
