Abstract

The current research focuses on the preparation of Al2219 with micron-sized ZrO2 composite using a liquid metallurgy technique. Al2219 alloy was used to make composites with ZrO2 particles. Microstructural analysis was performed on the created composites using SEM. Hardness, tensile strength and ductility were measured as per ASTM norms. Graphs taken using a scanning electron microscope showed that the boron carbide particles were evenly dispersed throughout the Al2219 alloy. The hardness, ultimate and yield properties of Al alloy were increased by adding ZrO2 particles. Further, Al2219 with 3 and 6 wt.% of ZrO2 composites showed lesser ductility than Al2219 material.
