اثر عمليات حرارتي بر كارآيي زره هاي كامپوزيتي آلومينا و آلومينيم 356 A

Effect of Heat Treatment on Alumina-Aluminum Alloy Composite Armour

In this research composite armour of pre-coated alumina balls in A356 cast aluminum alloys was made and then the role of solution and aging treatment on the microstructure and mechanical properties of this material was studied. The results show that all of mechanical properties increase with increasing the time of solution treatment. On the other hand the behavior of composite armour will change with the changing of aging parameters. Optimum mechanical properties of the armour are achieved by : solution treatment in 540 C for 8 h followed by water quenching and then aging in 180 C for 4.5 h.
