对Mg-3Zn-xSn(x=0.5,1.5,2.5,3.5)合金的热导率及拉伸性能进行研究。在25和100℃,测量了不同Sn含量合金的热导率,研究发现合金的热导率随着Sn含量的增加而下降,随着温度的升高而增加。同时,合金的抗拉强度和伸长率随着Sn含量的增加而增加。在铸造Mg-3Zn-(0.5~3.5)Sn合金中,发现热导率与拉伸性能是相反的。
The thermal conductivity and tensile properties of Mg-3Zn-xSn (x = 0.5, 1.5, 2.5, 3.5) alloys were investigated. The thermal conductivities of alloys with different Sn contents were measured at 25 and 100 ℃. It was found that the thermal conductivity of the alloy decreased with the increase of Sn content and increased with the increase of temperature. At the same time, the tensile strength and elongation of the alloys increase with the increase of Sn content. In the cast Mg-3Zn- (0.5 ~ 3.5) Sn alloy, it was found that the thermal conductivity and tensile properties are the opposite.
