- 摘要:
- 通过改变冷却速度及变质处理变质剂的含量对比研究变质处理及亚快速凝固对Al-7Si合金组织的影响。结果表明,亚快速凝固状态下的Al-7Si合金组织得到细化;亚快速凝固条件下,0.02%Sr变质处理效果最佳。The effects of modification and sub-rapid solidification on the microstructure of Al-7Si alloy were studied by changing the cooling rate and the content of the modifier. The results show that the microstructure of Al-7Si alloy is refined under sub-rapid solidification. Under the condition of sub-rapid solidification, the best modification effect was 0.02%Sr.
