- Abstract
- The Heusler intermetallic alloy CuTiAl was obtained via self-propagating high-temperature synthesis (SHS). The Cu2TiAl phase content in the combustion products of the Cu–Ti–Al system reached 96.2 wt.%. The microstructure and properties of the synthesized alloy were investigated. High-temperature X-ray diffraction analysis (XRD) demonstrated the phase stability of the alloy during stepwise heating and revealed that the anomalous behavior of the temperature-dependent electrical resistivity curve in the range of T = 770–790 K is not associated with phase transformations. A change in the sign of the Seebeck coefficient from negative to positive was observed upon heating at ~ 470 K.
