Effect of feeding technique in mechanical behaviour of Sic/Tio2 reinforced AA 6082 composites

Abstract

In this study, SiC and TiO2 nanoparticles reinforced AA 6082 composites were prepared by stir casting technique. The optimized quantities of reinforcement particles used in composites was 6 Wt.%. The mechanical properties such as tensile strength, compressive strength and hardness of prepared composites were improved significantly about with novel multi-encapsulate feeding as compared normal feeding technique. Also, the drastic improvement was noted with microstructure in order to form of health clusters and homogeneous distribution under novel feeding than normal feeding. The testing shows that the micro hardness and tensile strength was improved about 10% and 5% than normal feed process. Lesser blow holes and good matrix materials dispersion was found in multi encapsulate feeding process. From this experimentation, it was confirmed that multiple encapsulate feeding of reinforcement particles can increase the mechanical strength and microstructure properties than normal feed technique.
