Na-Ba复合变质对改良铸造铝-硅合金组织和性能的影响

Influence of Na-Ba compound modifier on structure and property of modified aluminum silicon cast alloy

以ZL101铝合金为基础,通过添加Cu、Ni、Mn、V、RE等合金元素,研制了改良铸造铝-硅合金,并研究了Na-Ba复合变质对该合金组织和性能的影响。结果表明,Na-Ba复合变质对改良铸造铝-硅合金是有效的,而且变质处理没有潜伏期,持续时间长,变质效果好。

The modified aluminum silicon casting alloy has been prepared on base of ZL101 alloy by adding alloying elements of Cu, Ni, Mn, V, RE ; and the Influence of Na-Ba compound modifier on structure and properties of modified aluminum silicon casting alloy has been studied. The result of investigation shows that the Na-Ba compound modifier is capable to improve aluminum silicon casting alloy, and there is not modification potential period, the modification action can have a longlast so the excellent modification effect can be obtained.
