Abstract

This paper describes a study of the structural and mechanical properties of Zn-matrix composites discontinuously reinforced by 7 wt.% SiC particles of size 0.7 µm. Commercial Zn-rich Zn–Al –Cu (ZA27) alloy was gas atomized, the resulting powder was mixed with a SiC powder and hot compacted into cylindrical pellets. Metal powder and powder mixture were pressed at 230°C for 60 min, under a pressure of 170 MPa. The compressive strength testing was performed in the temperature range from 20°C to 170°C with a deformation rate of 2.4 × 10 –3 s–1. Detailed microstructure characterization of samples has been evaluated by optical and scanning electron microscopy.

Keywords: Powder metallurgy; Microstructure; Mechanical properties; ZA27; SiC
