Fe2val
TīmeklisIndeed a variety of Fe2VAl-based thermoelectric materials have been developed, all of which exhibit a large enhancement in the Seebeck coefficient, in parallel with a sharp reduction in the electrical resistivity. The aim of this review is to survey our recent studies concerning the thermoelectric Tīmeklis2002. gada 1. jūl. · While the Heusler-type Fe2VAl (y = z = 0) exhibits a semiconductor-like resistivity behavior, a slight substitution of Ti or Mo for V causes a sharp …

TīmeklisFe2VAl has been focused as environment-friendly-material because it contains relatively plentiful and non-toxic elements. Theoretically, SHS method to produce Fe2VAl is much better than a conventional one because of lower energy consumption [1]. We already reported the possibility of producing Fe2VAl using self-propagating high-temperature ...
