【 摘 要 】

Aluminum alloys were as a rule used to fabricate in a few car and aviation parts. Al-Mg-Sc combination sheets were prepared a couple of cycles of Cross accumulative roll bonding (CARB) & similarly of accumulative roll bonding (ARB). In these two procedures Micro-structural advance have been occurring. It was clearly observed microstructure depicted by checking electron microscopy (SEM). In the midst of these both the system, Al-Mg-Sc alloys was adequately made with no disfigurement. In the midst of CARB process, Reinforcement (Mg, SC) particles reliably scattered inside Al system differentiated and similarly examined Al-Mg-Sc alloys in ARB process. In these two procedures, to incorporating of minor Sc in Al-Mg was extended hardness and besides it credited to the fine surface development. TEM imaging demonstrates development of fine hastens shaped inside grid in CARB contrast and ARB amid heat treatment. The Al-Mg-Sc alloy hardness was evaluated with using a Vickers hardness analyzer.
