Purpose: of the project was evaluation of the effect of heat treatment and of the reinforcing Ti(C,N) particles in the EN AW-AlCu4Mg1(A) aluminium alloy on the mechanical properties, wear resistance. Design/methodology/approach: some of the composite materials were hyperquenched for 0.5 h at the temperature of 495°C with the subsequent cooling in water, and were quench aged next for 6 h at 200°C. Hardness tests were made on HAUSER hardness tester with the Vickers method at 10 N. Abrasion resistance wear tests were carried out with the constant number of cycles of 5000 (120 m) at various loads: 4, 5, 6, 7, and 8 N. Test pieces were rinsed in the ultrasonic washer to clean them and next were weighed on the analytical balance with the accuracy of 0.0001 g to check the mass loss. Findings: Besides visible improvement of mechanical properties and wear resistance there were also observed the influence of heat treatment. Practical implications: Tested composite materials can be applied among others in automotive industry but it requires additional researches. Originality/value: It was demonstrated that the mechanical properties, as well as the wear resistance of the investigated composite materials with the EN AW-Al Cu4Mg1(A) alloy matrix may be formed by the dispersion hardening with the Ti(C,N) particles in various portions and by the precipitation hardening of the matrix.
