Effects of Roll Poreessing Rate and Heat Treatment on Microstuctures and Mechanical Properties of Ti75 Alloy Tube

摘要

The effects of deforming degree and annealling temperatures on performance of titanium alloy tubes Ti-75 are specified during 2-roller and multi-roller cold rolling process. The result shows that the alloy is sensitive for strain-hardening which has good cold processing performance by employing reduction 35%~40% for the cold rolling pass. The Ti75 alloy tube could obtain recrystallized structure with annealing at temperature 700~800t/1h/VC,and all quality and characteristic indications of thecold rolled products meet the requirement of technical standard.
