Conclusions
It was experimentally established that for electric discharge sintering of copper-abrasive composites the increase of abrasive concentration to 100% (1 g/cm3) affects the process substantially, while further increase to 200% does not have much effect.
For composites containing 100% (0–1 g/cm3) abrasive, the chief factor affecting the change in shock viscosity is the abrasive concentration, while the factor affecting the strength is the binder phase composition.
