| 摘 要： | 研究了钡盐加入量、变质温度和冷却速率等对钡盐变质铸造铝硅镁系合金组织和性能的影响。结果表明:随着钡盐加入量的增加,试验合金的变质效果越明显,但过多反而会使合金的组织和性能恶化;提高冷却速率对变质效果有利;钡盐变质最佳的温度为750℃左右,加入钡盐的最佳质量分数为1.0%;钡盐变质的长效性及重熔稳定性均很好。

| Abstract: | The effects of barium chloride additions,metamorphoic temperatures and cooling rates on microstructure and mechanical properties of as-cast Al-Si-Mg alloy metamorphosed by barium chloride was studied.The results show that the metamorphic effect of the tested alloy was more obvious with the increase of barium chloride adding content,but too much barium chloride was bad to the microstructure and mechanical properties of the alloy.Increasing cooling rate was benefit for metamorphoic effect.The best barium chloride metamorphic temperature was about 750 ℃ and the best barium chloride addition was 1.0wt%,and the long holding property and re-melting stable property of barium chloride metamorphosing was good. |
