Abstract
Lightweight and higher-strength materials are prevalent in many applications, such as aerospace, automobiles, and defence. The aim of this study is to develop and analyze the mechanical and microstructure properties of 1350-H19 (pure aluminium) reinforced with Zn-Al2O3 hybrid metal matrix composites (HMMCs). The fabrication of the HMMCs takes place via stir casting along with ultrasonic agitation. The hybrid composite material consists of various weight percentage of reinforcement like alumina (Al2O3) varies from 6 to 12 wt%, while the weight percentage of zinc is maintained at 5 percent. EDX and XRD result ensure the existence of reinforced particles in manufactured HMMCs. Taguchi's design parameter is used to optimize the number of experiments and find the ideal set of input parameters for the maximum micro hardness.The result shows that the mechanical properties such as UTS (Ultimate tensile strength) and hardness of the HMMC's improved considerably when compared to the base metal.
