【 摘 要 】

An experimental study of work-hardened metal release conditions and recrystallized structure formation with laser heating, which showed the possibility of these processes in low-alloy titanium was performed. Studies of treated materials properties showed that using of laser annealing enhances ultimate tensile strain and reduces minimum bend angle for cold deformation of rolled sheet metal parts of these materials. Using of laser annealing for local softening before shaping billets of titanium alloys allows to improve the accuracy of parts manufacturing by reducing their springy action. This provides an opportunity to expand their shaping options without additional heating.
