通过添加Ca到镁合金可以提高合金的阻燃性能,同时也研究了热处理对Mg-9%Al-1%Ca组织和性能的影响。结果表明,Mg-9%Al-1%Ca合金经过退火后,合金组织中出现连续或半连续的网状Al2Ca相,反而提高了合金的硬度;Mg-9%Al-1%Ca合金淬火后,晶粒变大,组织中出现Al2Ca,并以连续的网状相分布于基体,硬度增加。
The flame retardancy of the alloy can be improved by adding Ca to the magnesium alloy, and the effect of the heat treatment on the microstructure and properties of the Mg-9% Al-1% Ca is also studied. The results show that, after annealing, Mg-9% Al-1% Ca alloy appears continuous or semi-continuous reticular Al2Ca phase in the alloy, but increases the hardness of the alloy; Mg-9% Al-1% Ca alloy after quenching , The grains become larger, Al2Ca appears in the microstructure, and the matrix is distributed in a continuous network phase, and the hardness increases.
