Abstract

Composite materials with an aluminium matrix and ceramic reinforcement are becoming more popular in design application. The addition of AlN reinforcement increases the hardness of aluminium 7075 composite. In the current study, stir casting method was used to manufacture aluminium 7075-AlN composites by increasing the weight of AlN particles from 0 to 10 percent by a step of 2 weight percent. The As-cast and its composites underwent a solutionizing treatment for two hours at a temperature of 470° C, which was followed by extinguishing in different media, such as air, water, and ice. Then the specimens are subject to artificial ageing at 120c.microstructure analysis and hardness test was carried on both as cast and Al7075-AlN metal matrix composites. Al7075-AlN MMCs show an improvement in hardness when compared with Al7075.
