Readiness of Stir Casting 6061 Al-Al2O3 Metal Matrix Composites and Investigation of Wear and Mechanical Properties

Abstract

The automotive, aerospace, and marine sectors favorsaluminum metal matrix composites (AMCs) over conventional materials due to its remarkable attributes, such as superior resilience to wear and a high solidarity to weight ratio. The current study's objective is to blend metal lattice composite utilizing the mix projecting technique from the fluid metallurgy course, with 6061Al serving as the network material and ceramic Al₂O₃ particles for support. From support expansion level is being changed in increments of wt.%. Support particles for each composite were heated to 2000C and then distributed in groups of three into the liquid Al6061 compound vortex to promote wettability and circulation. For the aforementioned pre-assembled composites, microstructural representation was carried out using samples from the central portion of the material to ensure uniform particle dispersion. When Al₂O₃ particles expand, the prearranged features of hardness and malleability are not fixed, thus it is important to monitor the extent of advancement. The samples exhibit a degree of grain refinement and really uniform conveyance, as shown by the microstructural characterization of the composites. Furthermore, as compared to an unreinforced 6061Al network, composites have superior hardness and tractable characteristics. Similarly, increasing the amount of support has caused further expansion in both rigidity and hardness.
