Conclusions
In the electric-discharge sintering of a copper-tin composite raising the prepressing pressure from 4.17 to 12.5 MPa decreased the extent and rate of shrinkage by more than half. To attain the same hardness in the sintered copper-tin powder composite on passing from a low (4.17 MPa) to a higher prepressing pressure (12.5 MPa), it was necessary to resort to increasing the current density by 100 A/cm2 (from 595 to 695 A/cm2).
