Analysis of Microstructure and Orientation of Deformed TA15 Titanium Alloy with Different Heating Institution AITranslate
Abstract AITranslate
Isothermal compression tests of near-α TA15 titanium alloy were carried out on Gleeble 3500 thermal simulation machine. The influence was investigated of heating institution on microstructure and grain boundary or grain orientation of the deformed TA15 titanium alloy. The results show that when the alloy is deformed in the two-phase region （900 ℃）,its microstructure with ordinary heating institution consists of primary equiaxed a phase, recrystallized a phase and martensite α＇ phase, and its grain boundary ratio exhibits a peak value at the grain boundary misorientation of 40°, 60° and 90°. However, its micro- structure with β phase zone heating institution consists of lamellar martensite α＇ phase,β phase and interg- ranular a phase,and its grain boundary ratio exhibits a peak value at the grain boundary misorientation of 60° and 90° with enhanced grain preferred orientation. When the alloy is deformed in β single phase region （1 050 ℃）, its microstructure with ordinary heating institution has clear β grain boundaries and obvious cluster characteristics. However,its microstructure with βphase zone heating institution mainly consists of α＇ phase with greater length to width ratio, the original β grains disappear, and grain boundary ratio exhibits a peak value at the grain boundary misorientation of 60° and 90° with weakened grain preferred orientation and enhanced isotropics.
