| 摘 要： | 以ZLD11铝合金为研究对象,通过添加Sr来改变ZLD11铝合金的晶粒度,以达到细化晶粒的目的.介绍了ZLD11铝合金中元素的性质及作用,ZLD11铝合金的熔炼方法.以AlSr合金的形式加入熔体中,按照Sr的加入量占成品合金的0.04%,0.06%,0.08%以及0.10%来改变ZLD11铝合金的晶粒度,通过观察金相照片和测定晶粒度,来寻求合理的Sr的加入量,结果表明:采用X金属模铸造和用AlSr作为变质剂可以使ZLD11的晶粒细化,当Sr的加入量为0.08%时,细化晶粒效果最好.

| Abstract: | The ZLD11 alloys containing Sr have been prepared by adding AlSr master alloy and the refinement effect of Sr on the microstructure are investigated with different contents of Sr in the finish alloys such as 0.04%,0.06%,0.08%and 0.10% Sr to change the grain size of ZLD11 alloy in mass, both microstouctve observation and gain size statistical analysis have been used to discover the proper additions of Sr. The effects of the main alloying elements on properties of ZLD11 alloy, as well as the smelting process are introduced. The results indicate that AlSr master alloy as a crystal refiner with X metal mold casting process has an effective grain refinement for ZLD11 alloy, the best refinement effect were obtained with addition of 0.08% Sr. |
