Evaluation of Mechanical Properties of Rolled Cryo treated Al 6061–SiC Metal Matrix Composite (weldment) and Optimization using Design of Experiments (DoE)

Abstract

This study evaluates the mechanical properties of rolled cryo treated Aluminium 6061 reinforced with Silicon Carbide (SiC) particulates and optimizes process parameters using Design of Experiments (DoE). The composite was fabricated through stir casting and subsequently subjected to rolling under controlled parameters. Mechanical characterization included Yield Strength, Ultimate tensile Strength, Elongation, Hardness, and Impact Energy. Taguchi’s L9 orthogonal array was employed to identify optimal parameter settings for maximizing mechanical performance. Results indicate that reinforcement percentage and rolling reduction significantly influence the composite’s mechanical behaviour.
