Thermal Conductivity and Mechanical Properties of as-Cast Mg-3Zn-(0.5~3.5)Sn Alloys

摘要:

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。

Abstract:

The thermal conductivity and the tensile properties of Mg-3Zn-xSn (x=0.5, 1.5, 2.5, 3.5, wt%) alloys were studied. The thermal conductivities of the alloys with different contents of Sn were measured at 25 °C and 100 °C. The results clearly show that the thermal conductivity decreases with the increase of Sn content, and increases with the rise of temperature. Meanwhile, the ultimate tensile strength and the elongation of the alloys increase with the increase of Sn content. With the increase of Sn content the thermal conductivity of the alloys decreases, while the mechanical properties increase.
