Effect of Equal Channel Angular Pressing on Microstructure and Mechanical Properties of As-Cast Al-B4C Composite
In this experiment, comparison analysis of mechanical properties, porosity and grain size of Pure Al (powder), 95%AL + 5% B4C (With sand casting method) and 95%AL + 5% B4C (With ECAP method) are determined. The ECAP method value is much greater than the sand casting method,because of metal matrix composite microstructure refinement during the pressing operation. Because of material porosity value decreases, powder particle consolidation, the closure of porosity, grain refinement and improve in dislocation occurs as ECAP method gives the results of Mechanical properties as like tensile strength 105.8Mpa, Hardness 94HV, density 888.88kg/m3values increase. At the same time, porosity and grain size value will be reduced because of individual power consolidation happening during ECAP methods like as 1.63% and 8μm. In this metal matrix composite is applied to aeronautical and automobile industry
