The structure and mechanical properties of a powder composite with an AMg5 alloy metallic matrix reinforced with SiC particles have been examined. The composite with 3% reinforcing phase shows the best combination of strength, ductility, and damping capacity. Additional deformation processing of the composite improves its strength but reduces ductility because of planar pores observed on the fracture surface of severely deformed samples. It is shown that 30% strain hardening in the rolling process is not accompanied by reduction in ductility.
