Abstract
Abstract
This work presents the results of a study of the mechanical properties of a titanium alloy Ti-5Al processed by equal channel angular pressing (ECAP) and ultrasonic treatment (UST). The UST was carried out at a frequency of 20 kHz with an amplitude of oscillating tension-compression stresses of 100 MPa. It was shown that the alloy subjected to UST exhibited low temperature superplastic properties. Its elongation exceeded a value of 300%, the coefficient m was 0.3 at a strain rate of 1.7×10−4 1/s.
