摘要：

An alloy based on Ti-Al-Zr-Nb-V was prepared and its deformation behavior at elevated temperatures was studied. The microstructure and phase of the alloys were characterized by optical microscopy, scanning electron microscopy, thermal analysis, and mechanical testing. The results showed that the Ti-Al-Zr-Nb-V alloy, when stretched, exhibits a superplasticity effect in the range of 975 degrees C to 1100 degrees C, with an elongation of up to 400%. It was found that superplasticity develops in the temperature region of the alpha+beta ->beta transition and is accompanied by a change in grain size and redistribution of alloying elements among phases.
