Al—Mg合金是一种有广泛用途的铝合金,但实际应用时发现其铸造性能欠佳。人们常通过添加第三种微量元素来改善其铸造性能及一系列其他性质,使之满足各种需要。因而人们颇为注意第三种元素M(M为周期表中的所有金属元素)与Al—Mg合金形成的三元系的各
Al-Mg alloy is a widely used aluminum alloy, but its practical application found that its casting performance is poor. People often improve the casting properties and a series of other properties by adding a third trace element to meet a variety of needs. Therefore, people pay more attention to the third element M (M is the periodic table of all the metal elements) and the Al-Mg alloy ternary system each
