<p>Aluminum-based composites provide elevated strength-to-weight ratios, enhanced wear resistance, and thermal stability, addressing the increasing demand for innovative materials in fields of automotive, aerospace, and industrial sectors. The need of the innovative materials has urged the researchers to carry out the research work in this field. This study explores the effect of the addition of zirconium carbide and Flyash to the LM 13 aluminum matrix. Composites were manufactured by the combined stir and squeeze casting process. Microstructural studies were carried out with the help of scanning electron microscope (SEM) and the element analysis was carried out with an energy-dispersive x-ray (EDX). X-ray diffraction (XRD) analysis was used to study the phase identification. Mechanical characterization was carried out by tensile strength, impact strength, compressive strength, and Vickers hardness. SEM was used to study tensile and impact strength in fractography. EDS studies confirm the presence of fillers, as revealed by microstructural images. XRD studies revealed the addition of reinforcement. Mechanical analysis demonstrated that the incorporation of reinforcement led to a rise in mechanical characteristics like tensile strength (197&#xa0;MPa), compressive strength (589&#xa0;MPa) and hardness (172 HV) in the case of T4 samples while impact strength was maximum at T3 sample (0.022&#xa0;J/mm). Fractographies of the impact and tensile strength showed the presence of dimples, brittle fractures, ductile fractures, and cleavage facets.</p>
