Influence of strain rate and temperature on the friction factor of commercialy pure titanium

In this investigation, ring-compression tests have been carried out on commercially pure titanium, both with the recommended lubricant MoS2 and without lubricant, to evaluate the interface constant shear friction factor. The tests were conducted in the temperature range of from 303 to 573 K and the strain-rate range of from 0.07 to 32 s-1. The results of the investigation reveal that the friction factor for the combination commercially pure titanium (as the work material) and high-speed steel (as the tools) increases with strain rate and temperature and that MoS2 is a satisfactory lubricant up to a temperature of 473 K. © 1990.
