摘要
采用定向凝固技术,研究了一定温度梯度下不同拉伸速度对Mg-3Zn-Y合金导热性能的影响。研究表明,随着拉伸速度的增加,柱状晶的平均宽度逐渐变窄,合金的热导率先增加后降低。
By adopting the directional solidification technology＇, the influence of different stretching velocities under a certain temperature gradient on the thermal conductivity of Mg-3Zn-Y alloy has been studied. The results show as the stretching velocity increases, the average width of columnar crystal narrows clown gradually, and the thermal conductivi- ty of alloy increases at first and then decreases later.
