摘要：
The flow behavior and hot deformation mechanisms of Ti-6Al-4Vin both beta and (alpha + beta) phase regions have been studied by compression tests in the temperature range 750 - 1100 degrees C and strain rate range 0.05 -15 s (-1). The flow curves displayed discontinuous yielding at temperatures above 850 degrees C and high strain rates, typically 5 and 15 s(-1). Flow oscillations were also observed under such conditions. The relative discontinuous flow stress drop increased with increasing temperature in the (alpha + beta) phase region and reached a steady state in the beta phase region. The d...
