Investigation of mechanical and machinability properties of Al2O3/SiCp reinforced Al-based composite fabricated by stir cast technique

摘要

The paper presents the results of experimental investigation on mechanical and machinability properties of A332-Al2O3/SiCp reinforced using varying size of particles up to 53 mu m by a vortex method was carried out at different cutting conditions. Experiments were carried out with TiN (K10) coated carbide tools and TP30 coated carbide tools at various cutting speeds The influence of reinforced ratios of 10 wt% of Al2O3/SiCp on mechanical properties was examined. The effect of machining parameters, e.g. cutting speed, feed rate and depth of cut on flank wear land and surface roughness was studied. It was observed that decreased with increasing the particle size produced better mechanical properties such as tensile strength and hardness, but wear showed different trend; increased with decreasing the particle size. Machinability properties of the selected material were studied and with increasing the particle size surface roughness was generally affected by feed rate and cutting speed.
