This experiment, comparison analysis of micro structural properties, and grain size of Pure Al (powder), 95%AL + 5% B4C and 90%AL + 10% B4C (With ECAP method & stir casting) are determined. Based on the micro structural analysis using SEM, the particle distributions of AL- B4C were analysed. The powdered sample were fabricated using equal channel angular pressing (ECAP) and stir casting process. When observed using SEM it was found that the particle distribution homogeneity increased as the number of passes increased from one to four. The factors such as Temperature, number of passes are to be considered in the development of grain structure and refinement. The results show that: the amount of shear strain and the mobility of metal matrix have the most important influence to the uniform distribution of particles Al? B4C. In this work, the mixtures of B4C particles and Al powders were fabricated into sever plastic deformation using ECAP and stir casting. And the effects of different ratios, positions and deformation stages on the distribution of B4C particles were investigated.
