Highlights: [•] Using high velocity compaction we compact Cu–0.9Al2O3 composite powder. [•] At impact velocity 9.4m/s the relative green density was obtained 96.8%. [•] Axial and radial shrinkage increased with increase in sintering temperature. [•] The mechanical properties were improved with an increase sintering temperature. [Copyright &y& Elsevier]

Highlights: [•] Ti–10Mo alloy powder has been compressed by high velocity compaction technique. [•] Density of compacts depends on impact force per unit area of powder filled in die. [•] Maximum relative green density of the compacts was obtained 90.86% at 1615Nmm−2. [•] Spring back of compacts decreases with the increment of impact force. [•] Impact force per unit area affects the mechanical properties of the compacts. [Copyright &y& Elsevier]
