Abstract

Determining the sintering parameters is decisive for optimizing the tribological, physical and mechanical perfomance of aluminum matrix alloys. In parts produced by powder metallurgy, the sintering stage directly determines the density, microstructural development, and the strength of metallurgical bonding between particles. The present study investigates the thermal behavior of Al–4.4Cu–1.5Mg produced by powder metallurgy-produced Al–4.4Cu–1.5Mg using TGA/DTA and evaluates the effects of selected sintering temperatures on the microstructure, hardness, and wear performance. The experimental results showed that increasing sintering temperature increased the relative density from 93.72% to 95.54% and the hardness from 74.3 HB to 79.3 HB. In contrast, the tribological test results showed that increasing the sintering temperature from 605 °C to 625 °C increased the wear volume from 0.5797 mm3 to 1.2132 mm3 and the coefficient of friction from 0.556 to 0.587. Overall, the evaluation of the mechanical properties, microstructure and wear performance, the optimal sintering temperature for Al–4.4Cu–1.5Mg was determined as 605 °C.
