Electrical Resistance, Magnetic and Thermoelectric Properties of the Heusler Alloy Co2TiAl Obtained by Self-Propagating High-Temperature Synthesis
摘要
Abstract
A thermoelectric Co2TiAl alloy was obtained by the SHS-metallurgy method for the first time. The microstructure and the magnetic and thermoelectric properties of the synthesized alloy were investigated. The maximum value of the Seebeck coefficient and thermoelectric power at room temperature were ‒29.5 μW/K and 1230 μW m–1 K–2, respectively. The comparison of the influence of the SHS-method modifications on the properties of the synthesized alloy was made. It has been shown that the alloy synthesized by SHS pressing has higher thermoelectric characteristics than the alloy obtained by the SHS-metallurgy method.
