Description
Summary:In the present study, an attempt has been made to synthesis Al7050/B4C Aluminium metal matrix composites using electromagnetic stir casting method under various mass percentage of reinforcement. Metal matrix composites were produced by reinforcing B4C particles with differing weight percent by 3, 6 and 9 using the stir casting process. The efficiency of the composites was contrasted with the alloy in order to study the enhancement of the mechanical properties of the reinforcing particles to the composites. Increasing the weight percent of B4C particles in the aluminum matrix increases the hardness of the composites relative to the alloy due to the resilience of the reinforcement particles to plastic deformation. The tensile strength of the composites greatly increases up to 6 wt% of the reinforcement and after that the increase in tensile strength is reduced due to the clustering of the reinforcement particles. Micro structural studies have been performed using a scanning electron microscope (SEM) that shows uniformity.
