摘要

研究了ZAlSi7Mg1合金砂型铸造时细晶料对其组织和性能的遗传效应。首先通过对比分析砂型铸锭和金属型铸锭重熔后试样的组织和力学性能

证明了组织的遗传性。然后利用质量分数为10%的ZAlSi7Mg1的挤压铸造细晶料

证明了其对砂型铸件组织和性能的遗传作用。ZAlSi7Mg1合金中加入10%的挤压铸造细晶料保温20min可以有效地细化砂型铸件组织。

Abstract

Heredity effects of fine-grained materials in ZAlSi7Mg1 alloy in sand casting were examined.Heredity of fine-grained structure was confirmed by comparatively analyzing microstructure and mechanical properties of re-molten ZAlSi7Mg1 alloy ingot in sand casting and in permanent mold casting.Heredity effects of 10% squeezing-forging fine-grained ZAlSi7Mg1 alloy on structure and mechanical properties of the alloy in sand casting were examined.The results show that the structure of ZAlSi7Mg1 alloy in sand casting can be evidently refined by adding 10% squeezing-forging fine-grained ZAlSi7Mg1 materials with holding for 20 min.
