摘要：

Samples of Ti-3Al-5V-5Mo alloy were compressed in both beta and alpha + beta phase region on a Gleeble 1500 Simulator. Compression tests were carried out in the temperature range of 700-1000 degreesC and strain rate range of 0.05-15 s(-1). Experimental results show that the flow stress of Ti-3Al-5V-5Mo alloy decreases with the increase of temperature and the decrease of strain rate. At high strain rate, typically 5 and 15 s(-1), discontinuous yielding followed by flow oscillations was observed in both beta phase region and alpha+beta phase region; at low strain rate, the flows display single p...
