Abstract
This is articles, the need for lightweight materials for Equipments, Aircrafts, vehicles and space stations, has become imperative. In view of this, Micro structural analysis of Aluminum alloys becomes very essential in establishment of their physical properties. The samples will be cast and heat treated at 450 oC for 1 hr, after which the samples will be annealed, and quenched in used engine oil and water. Tensile and hardness tests will be carried out on the samples. The ultimate tensile strength observed which will be increased with decreasing quench severity of quench media. The samples will be characterized by hardness as-cast, annealed, used engine oil quenched and water quenched samples. The results will show that the hardness increased with increasing quench severity. And test samples will be investigated their Mechanical properties and their numerical analysis will be taken and compared by finite element analysis.
