Abstract
The paper examines the structure density resistivity and mechanical properties of Cu–50 wt Cr powder composite after liquidphase sintering at 1200°C in hydrogen and subsequent deformation processing additional cold pressing under 550–600 MPa sintering under 85 MPa at 1100°C and hot forging beginning from 850°C It is shown that the maximum compaction of the composite up to 99 of the theoretical density decrease in its resistivity and increase in strength and plasticity are reached in hot forging in a closed die mold and subsequent annealing at 600°C to relieve internal stresses
