Ultrasonic Treatment of Ti-5Al-0.5 V Alloy Subjected to Equal-Channel Angular Pressing

Abstrakt

Microstructure and room temperature mechanical properties of α-titanium alloy Ti-5Al-0.5 V subjected to equal channel angular pressing (ECAP) and subsequent ultrasonic treatment (UST) have been studied. The ECAP was carried out at 600 °C by route Bc and the UST at the frequency of 20 kHz and amplitude of compression-tension stresses of 100 MPa for processing time of 60 s.
