Structure and Properties of PM Composite Materials Based on EN AW-AlCu4Mg1(A) Aluminium Alloy Reinforced with the Ti(C,N) Particles
Investigations of composite materials based on EN AW-Al Cu4Mg1(A) aluminum alloy reinforced with the Ti(C,N) particles with various weight ratios of 5, 10 and 15% are presented. The metallographic examinations of composite materials show banding of the reinforcing particles in aluminum matrix after extrusion process. Structure oriented in parallel with extrusion direction is observed in composites materials. Portion of reinforcement particles Ti(C,N) has influence on the mechanical properties of composite materials. The increase of hardness, abrasive wear and decrease of compression strength, tensile strength is observed with the portion growth of reinforcement particles.
