| 제목 | Synthesis and thermoelectric properties of Half-Heusler TiCoSb |
| 초록 | Half-heusler alloys are one of the potential thermoelectric materials for high temperature application. In an attempt to produce half-heusler thermoelectric materials with fine microstructures, TiCoSb was synthesized by mechanical alloying of stoichiometric elemental powder compositions, and consolidated by vacuum hot pressing. Phase transformations during mechanical alloying and hot consolidation were investigated using XRD and SEM. Single-phase, half-heusler was successfully produced by mechanical alloying process, but a little portion of 2nd phase of CoSb formation was observed after vacuum hot pressing. Thermoelectric properties as functions of temperature were evaluated for the hot pressed specimens. Mechanically alloyed half-heusler phase, TiCoSb, appeared to have a great potential for high temperature thermoelectric materials in this study. |
