Mechanical Alloying for Making Thermoelectric Compounds

[摘要] An economical room-temperature mechanical alloying process has been shown to be an effective means of making a homogeneous powder that can be hot-pressed to synthesize a thermoelectric material having reproducible chemical composition. The synthesis of a given material consistsof the room temperature thermomechanical-alloying process followed by a hot-pressing process. Relative to synthesis of nominally the samematerial by a traditional process that includes hot melting, this synthesis is simpler and yields a material having superior thermoelect ric properties.
