Aging behavior and tensile properties of 6061Al–0.3 μm Al2O3p particle composites produced by reciprocating extrusion

6061Al–0.3 μm Al2O3p composites are fully densified from powder compact by reciprocating extrusion. Al2O3 particles are dispersed uniformly in the matrix. The composites exhibit excellent ductility caused by the mechanical kneading of reciprocating extrusion.
