摘要：

Hot compression tests were carried out on commercially pure titanium grade 2 at temperatures below the beta-transus (915 degrees C). At temperatures of 840, 860, 880, and 900 degrees C, the beta volume fraction increased by 30%, 32%, 36%, and 55%, respectively. The minimum temperature at which dynamic transformation could be induced was 765 degrees C. The driving force for transformation given by the net softening associated with the formation of the lower flow stress beta phase was calculated to fall in the range between 200 and 500 J/mol.
