Thermoelectric properties of an alloy based on the Al–Mn–Si system, produced by SHS pressing
https://doi.org/10.22349/1994-6716-2024-120-4-37-45
Abstract
A thermoelectric alloy containing the Mn5 (Si2.5Al0.5) phase was obtained for the first time using self-propagating high-temperature synthesis combined with pressing. The microstructure of the alloy is represented by grains up to 10 μm in size. X-ray phase analysis showed the presence of the following phases in the synthesized sample: Mn5 (Si2.5Al0.5), TiC and SiO2. The presence of the TiC and SiO2 phases is due to the specific features of the sample synthesis using the SHS pressing method. A study of the thermoelectric characteristics of the material was conducted. The value of the Seebeck coefficient (S) at room temperature is about 8 μV/K and reaches a wide maximum of 9–10 μV/K at T = 360 K, and the maximum value of specific electrical resistance of 1.5∙10-2 Ohm∙cm is achieved at room temperature.
