The focus of the present investigation is to enhanc e mechanical properties of two-stage stir cast Al606 1-B4C (2, 4 and 6 wt.%) reinforced metal matrix composites by artificial aging treatment. The Optical and Sca nning Electron Microscope show homogeneous distribution of reinforc ements in the aluminum matrix. The composites were solutionized at 558OC for 2 h and followed by water quenching. The sample s were subjected to aging treatment in the range of 100, 150 and 200 OC for different time intervals. Lower aging temperatu re and higher aging time show substantial enhancement in hardness and tensile str ength. Around 170% improvement in hardness and 100% improvement in tensile strength values were observed when aged at 100OC with an increased weight percentage of reinforced particulates as compared to the unreinfo rced Al6061 alloy.
