Speculative Testment of Heat Treated Aluminium MMC

In the current work, nickel-coated hBN with Al7075 has better property. when Unalloyed material compared with Al7075. The hybrid reinforced composite exhibits & excellent hardness property, due to the addition of nickel coated hBN particles in the Aluminium 7075 matrix. The Vickers hardness number for Al7075 + 4.5% nickel-coated hBN shows a high hardness value compare with the base metal. An additional heat-treated at 100 0c in a muffle furnace for 11hours and water quench its hardness show a high value as compare to the base metal. Also the hybrid reinforced composites exhibit excellent tensile property; as compared with base metal (Al7075) and Al7075+4.5% nickel-coated hBN show high Breaking Load and Ultimate Tensile Strength. Thus by investigating the hardness properties for both hybrid composite and base metal, it is found that the hardness of hybrid metal matrix composite plates was higher when compared to Al7075 alloy. The critical inferences of results of project work conclude that the Hybrid Aluminum 7075 metal matrix composites have a better hardness and tensile property than the base metal, at the expense of ductility.
