A Study on the behaviour of Aluminium alloy (LM13) reinforced with NanoZrO2Particulate

Abstract

The present work analyses the characteristic behaviour of the Aluminium alloy (LM13) reinforced with nano-zro 2 particulates by Stir Casting technique. The experimentation is carried out by distribution nano-zro 2 particles of size varying from 50-80nm and quantity ranging from 2-10 wt. %. The composite synthesized is analysed and evaluated in various aspects of strength ,ductility, porosity and hardness by adapting microstructural, mechanical and fractographic techniques and it is arrived that the Nano composite developed has significantly improved strength, hardness, retains residual porosity while compromising slightly with of the resultant composite. The Al-NanoZr0 2 composite thus synthesised displays a significantly reduced Electrical Resistivity and Thermal conductivity.
