抄録

The formation process of Mg<SUB>2</SUB>Si based thermoelectric composite made by mechanical alloying was investigated.<BR>The MA was performed in a planetary ball mill using three elemental powders. The powders were prepared by the mixing of Mg<SUB>2</SUB>Si, Mg<SUB>2</SUB>Si-xmass%SiC(x=4, 8) and Mg<SUB>2</SUB>Si-xmass%FeSi<SUB>2</SUB> (x=20, 40, 60, 80, 100). The structural evolution during milling was detected by X-ray diffraction(XRD). The heat treatment was monitored by differential scanning calorimetry(DSC). Microstructural changes were mainly investigated by means of scanning electron microscopy(SEM) and optical microscopy(OM).<BR>The formation of the Mg<SUB>2</SUB>Si phase is observed after milling for 1080ks under At atmosphere. But the milling time to form Mg<SUB>2</SUB>Si became shorter by milling with including another element such as Fe, Si, N and SiC. The structure of Mg<SUB>2</SUB>Si milled under N<SUB>2</SUB> atmosphere became most fine. For Mg<SUB>2</SUB>Si-xmass%FeSi<SUB>2</SUB> including less than 60mass%FeSi<SUB>2</SUB>, the phase of Mg<SUB>2</SUB>Si, FeSi, Fe and Si were observed in the powder milled after 360ks. On the other hand, for Mg<SUB>2</SUB>Si-80mass%FeSi<SUB>2</SUB>, the phase of Mg<SUB>2</SUB>Si and FeSi was not observed but Fe and Si was only observed independent on milling time.
