Problems solved by technology

In order to better enhance the performance of titanium alloys, it is usually necessary to carry out cold strengthening treatment, specifically to plastically deform the titanium alloy sheet to enhance its hardness and strength, but in this process, the plasticity of the sheet is usually caused. In order to enhance its comprehensive performance, it is usually necessary to improve the plasticity of the plate; in addition, micro-damages such as internal cracks and pores will appear during the processing or use of this type of plate. Handling will cause safety hazards such as deformation and breakage
At present, there is no effective method to improve the plastic properties and damage repair of titanium alloy sheets.
