A fabrication and Micro structural study of Al-6061 Metal Matrix Composites

摘要

The main objective of the present works related to the material characterization of fabricated Al-6061 by stir casting technique as increasing percentage by weight and the particle size of B_4C increased their strengthening effect and a distinct advantage is the ability to use many combinations of resins and reinforcements especially in aerospace industry. Furthermore, the effects of reinforced particles sizes on the micro structure of the composites were observed by using SEM. The finer particles will provide more efficient barriers to dislocation flow in aluminum matrix and more homogeneously distributed. Larger particles are more susceptible to gravity settling and can result in clustering and agglomeration of reinforcement in matrix region. aluminum metal matrix composites.
