Study on Microstructure and Mechanical Properties of High Strength Titanium Alloy Cold-Rolled Tubes AITranslate
Abstract AITranslate
Cold compression tests of Ti-1300 alloy were carried out by Gleeble—3800 simulated testing machine.The effects of extrusion temperature,cold rolling reduction and heat treatment on the microstructure and mechanical properties of Ti-1300 alloy cold-rolled tubes were investigated through tensile tests at room temperature and microstructure observation.The results show that the Ti-1300 alloy cold-rolled tubes with 30% reduction extruded at the transformation temperature have a good strength-plasticity match.After solid solution treatment,cold-rolled tubes have lower strength and better plasticity,and the α+β two-phase solid solution microstructure mainly consists of a large number of spherical or elongated α phase and resi-dual metastable β phase.The β phase solid solution microstructure is mainly composed of equiaxed β grains.The strength of cold-rolled tubes in aging state is significantly improved,and their microstructure is mainly composed of spherical or elongated primary α phase,acicular secondary α phase and β matrix.
