摘要

这项工作的目的是多方面的：首先，通过机械合金合成均质的 Bi/sub 85/Sb/sub 15/ 多晶粉末合金，球与粉末的重量比为 10:1；其次，通过烧结或热挤压固结粉末，尝试在材料中引入纹理；最后，测量固结样品在 77-300 K 温度范围内的热电特性。

Influence of the consolidation technique on the thermoelectric properties of mechanically alloyed Bi-Sb

The aim of this work is multiple: first the synthesis by mechanical alloying of homogeneous Bi/sub 85/Sb/sub 15/ polycrystalline powder alloys, that have been achieved with an adequate ball to powder weight ratio (10:1), second the consolidation of the powders either by sintering or by hot extrusion in order to try to introduce a texture in the material and finally to measure the thermoelectric properties of the consolidated samples in the 77-300 K temperature range.
