Abstract :
The aim of this work is multiple: first the synthesis by mechanical alloying of homogeneous Bi85Sb15 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
