This study investigates the development of Al6061-based Hybrid Metal Matrix Composites (HMMCs) reinforced with nickel (Ni) and chromium (Cr) to enhance their mechanical properties. Employing the stir casting method, the research aimed to achieve a homogeneous distribution of Ni and Cr particles, varying from 1 to 3 wt.%, in the Al6061 matrix. Additional elements like graphite (up to 3 wt.%) and magnesium (1 wt.%) were incorporated to improve selflubrication and wettability. The fabrication process involved precise temperature control at 750°C and automatic stirring to ensure even dispersion of the reinforcing particles. The composites were then molded, solidified, and prepared for mechanical testing. SEM-EDS analysis was utilized to analyze the elements' distribution and the composites' microstructural integrity. Mechanical tests, including tensile, flexural, and hardness tests, followed ASTM standards. Significant findings revealed that the specimen with two wt.% Ni and two wt.% Cr (designated as SM2) demonstrated the most balanced improvement in mechanical properties: a tensile strength of 236.08 MPa, a flexural strength of 417.70 MPa, and a hardness of 127.00 HRB. However, an increase in Ni and Cr content beyond 4 wt.% led to non-homogeneous dispersion, manifesting as cracks, voids, and agglomeration, negatively impacting ductility and elongation properties. The study's unique contribution lies in its detailed examination of the effects of varying Ni and Cr concentrations on the mechanical properties of Al6061-based composites, providing valuable insights for material optimization in highperformance applications. This research underscores the delicate balance required in composite material design, particularly in enhancing specific mechanical properties without compromising overall material integrity. It provides crucial insights into the role of Ni and Cr reinforcements in Al6061 composites, highlighting their potential for engineering applications that demand high strength, flexibility, and hardness.

Aluminium alloys are popular in many advanced applications and are considered to be an essential class of engineering materials mainly due to their desirable combination of low density, high strength, and cost-effectiveness compared to competing materials. Aluminium metal matrix composites and hybrid metal matrix composites will further enhance these properties by incorporating hardened particles as reinforcements. Hybrid metal matrix composites are second-generation composites that exhibit superior mechanical properties due to the synergistic combination of different reinforcement combinations. Various combinations of reinforcing particulates are being explored. The fabrication of the hybrid composites is done using a stir casting route, which will significantly influence the mechanical properties, microstructure and reinforcement distribution. Aluminium HMMCs offer lightweight, high strength, good wear resistance, and other properties that allow them to be extensively used in the structural, aerospace, marine, and automotive industries. Hybridization of metal alloys provides flexibility in designing components and quality control during manufacturing. Thus, this review paper is focused on the fabrication and characterization of hybrid Aluminium metal matrix composites, advancements in their mechanical properties, recent developments and applications.
