    摘要:

    制備鑄態(tài)Mg-1Ag-Zn, Mg-3Ag-Zn 和 Mg-5Ag-Zn合金試樣，并計(jì)算其導(dǎo)熱率。隨著Ag含量的增加，鑄態(tài)合金試樣的導(dǎo)熱率減少。再將其鑄態(tài)合金的試樣以三種不同的定向凝固速率（v=25μm/s, v=50μm/s, v=75μm/s）制備成定向凝固試樣，計(jì)算其定向凝固試樣的導(dǎo)熱率。結(jié)果顯示：隨著定向凝固速率的增加，合金的導(dǎo)熱率降低。合金中溶質(zhì)元素的含量與定向凝固速率是影響導(dǎo)熱率的重要因素，這兩個(gè)因素可以增強(qiáng)電子和聲子的散射過(guò)程，減少自由行程，最終降低合金的導(dǎo)熱率。

    Abstract:

    Specimens of as-cast Mg-1Ag-Zn, Mg-3Ag-Zn and Mg-5Ag-Zn alloys were fabricated, and then the specimens’ thermal conductivity was calculated. With the increase of Ag content, the thermal conductivity decreased significantly of as-cast alloys. After that, directional solidified specimens of the above mentioned as-cast Mg-Ag-Zn alloys were made at three different pulling velocities: V=25μm/s, V=50μm/s, V=75μm/s, and then again calculated their thermal conductivity. The result showed that with the increase of the pulling velocity, the thermal conductivity of alloys decreased significantly. Variations in the solute content and the pulling velocities are believed to play important roles on the thermal conductivity of Mg- Ag-Zn alloys. Since those two circumstances can strengthen the electron’s scattering process, reduce their free path, and thereby reduce the alloys’ thermal conductivity.
