|Title:||Experimental studies on mechanical properties of T6 treated Al25Mg2Si2Cu4Fe alloy|
|Citation:||AIP Conference Proceedings, 2018, Vol.1943, , pp.-|
|Abstract:||Effect of T6 treatment on the mechanical properties of Al25Mg2Si2Cu4Fe alloy was evaluated by conducting mechanical tests on test pieces using universal testing machine. Increase in the mechanical properties such as ultimate tensile strength, hardness and % elongation was observed. Microstructure characterization revealed the modification in the size and shapes of the precipitates formed during the homogenization process. This modification increases the anisotropy of the microstructure and the stresses in the as cast structure. The increase in the hardness of T6 treated alloy is due to the partial recrystallization, fragmentation and redistribution of primary Mg2Si phase, precipitation of fine ?, Q phases. The high volume fractions of uniformly dispersed hard ?-particles greatly increase the flow stress and provide an appreciable impediment to plastic deformation. Thus increasing the hardness of the alloy. � 2018 Author(s).|
