Nanoscale microstructural analysis and evaluation of mechanical properties were conducted on severely cold-rolled aluminum alloys. In order to examine the effect of alloying elements on microstructure and mechanical properties, Al-Cu-Mg, Al-Mg-Si and Al-Zn-Mg-Cu alloy sheets were prepared for systematic investigation. The SAXS and SANS were used to analyze the nanoscale microstructures in solution-treated and rolled samples of Al-Cu-Mg and Al-Zn-Mg-Cu alloys, and the results quantitatively revealed that nanoscale clusters are formed regardless of with or without rolling. HR-TEM, HAADF-STEM, thermal analysis, hardness and electrical conductivity measurements also suggested that the clusters are formed in cold-rolled samples. Mechanical property evaluations showed that strength generally increased, and ductility decreased with increasing cold-rolling reduction. The strength tended to increase with increasing solute content regardless of the alloy system. [ABSTRACT FROM AUTHOR] |
