摘要
Abstract
The effects of Sc on microstructure, recrystallization temperature and mechanical properties of Al-Mg alloy were studied by optical microscope, hardness measurement, tensile testing and TEM techniques. The results show that Sc can improve the mechanical properties effectively, prevent the recrystallization of Al-Mg alloy,The dispersed secondary Al(Sc,Zr) phase precipitated from a( Al) is coherent with the matrix after high temperature annealing resulting in high recrystallization temperature and tensile properties of 1570 alloy.关键词
