| Abstract Scope |
This paper reports the correlation between microstructure evolution and mechanical properties of Al-Mg-Si alloy fabricated by cryogenic differential speed rolling (CDSR). The combination of cryogenic treatment with differential speed rolling (DSR) effectively increased mechanical properties without an appreciable decrease in ductility through the ultrafine grained the Al-Mg-Si alloy. For this purpose, the Al-Mg-Si alloy has been subjected to DSR process at a cryogenic temperature of -183.2°C and the results were compared with that processed via DSR. Microstructural analyses using optical image (OM) and electron backscattered diffraction (EBSD) measurements showed that the samples with CDSR resulted in ultra-fine grain with improved uniformity as compared to that processed with DSR. In addition, uniformity of mechanical properties for the samples via CDSR was higher than that via DSR. |
