The study investigates the properties of aluminum-matrix composites in the Al-TiC, Al-SiC, and Al-Si-Ni systems. The effect of thermal treatment (annealing) was examined, revealing that while it does not alter the phase composition, it reduces the coherent scattering region in Al-TiC and influences its coefficient of thermal expansion (CTE). For Al-SiC, the CTE dependence on SiC content, sintering temperature, and copper addition was established. In Al-Si-Ni and Al-SiC composites, CTE increases after annealing, whereas in Al-TiC, it decreases. Based on these findings, recommendations were developed to optimize the composition and manufacturing process of these materials, enhancing their performance in thermal management systems, precision mechanisms, and load-bearing structures.
