Abstrakt: This article describes the study of the thermal expansion coefficient of a TiNbTaZr alloy by a dilatometric differential method used to determine phase transformation temperatures. The object of the study was samples of an alloy of TiNbTaZr with a variable composition, which underwent homogenizing annealing and rotary forging. According to the obtained results, all the studied alloys have three temperature regions, which are distinguished in the graphs of uniform elongation with increasing temperature.
