The Effect of Heat Treatment on Mechanical Properties of Aluminium Alloy 7075 with Nano B_4C

摘要

The mechanical behavior of Al7075 alloy composite reinforced with 3%, 6% by weight ratio nanosized B_4C particulate is investigated with and without heat-treatment process. The composite is prepared by liquid casting - stirring method and mechanical behavior of alloy Al7075-3% weight (wt) and B_4C, 6% wt and B_4C nanocomposites were deliberated. Hardness, ultimate tensile strength; yield strength, percentage elongation and compression strength were evaluated and compared as per ASTM standards. The findings yielded in significant enhancement of properties after heat-treatment process. Only percentage elongation of the composite showed declined value relatively.
