不同于B95合金的B95合金相应地有害杂质铁和硅的含量小,因而,未因溶的金属间化合物的量比B95中的少,这些化合物使材料的可靠性降低。这说明在构件中,B95合金具有高的抗应力集中性。B95合金的热处理规范与B95合金的相似。但是,铁和硅杂质含量的减少不但对铝内未溶的金属间化合物相数量有影响,而且对合金的临界点位置有影响,从而影响淬火加热温度。本文的目的是:探讨提高B95合金(5~7%Zn;1.8~2、8%Mg;1.4~2.0%Cu;0.1~0.25%Cr;0.2~0.6%Mn)淬火加热温度的可能性,以便使固溶体内的大量强化相溶解和提高在随后时效时的强化效果。
The B95 alloy, which is different from the B95 alloy, accordingly has less harmful iron and silicon impurities and therefore less unmelted intermetallics than in B95, which compounds lower the reliability of the material. This shows that the B95 alloy has a high stress concentration resistance in the component. B95 alloy heat treatment specifications and B95 alloy similar. However, the reduction of iron and silicon impurity content not only affects the amount of undissolved intermetallics in the aluminum but also affects the critical point of the alloy, thus affecting the quenching temperature. The purpose of this paper is to explore the ways to improve the mechanical properties of B95 alloy (5-7% Zn, 1.8-2,8% Mg, 1.4-2.0% Cu, 0.1-0.25% Cr, 0.6% Mn) to quench the heating temperature in order to dissolve a number of reinforcing phases in the solid solution and to enhance the strengthening effect on the subsequent aging.
