A method of producing a high-density abrasive compact material includes the steps of providing an electrically conductive mixture of a bonding powder material and abrasive particles or grit; compressing the electrically conductive mixture; and subjecting the

Electromigration and the electroplastic effect in …

Aluminum SiC metal-matrix composites fabried by standard powder-metallurgy compaction and sintering were subjected to high-density alternating-current pulses during transverse rupture testing. Results indie increased strength due to electromigration. Decreases in flow stress were observed during plastic deformation and were attributed to the electroplastic effect.
