摘要
Abstract
Through comparative analysis of microstructural properties of sheets processed via different hot working processes while avoiding cold rolling,an optimal process scheme was developed to address the poor matching between mechanical properties and bending formability of 4.0 mm TA5 sheets,thereby facilitating high-quality industrial mass production.The research indicates that β-quenching combined with warm rolling at 550℃ can rapidly refine slab microstructure by introducing multi-dislocations and substructures,effectively enhancing sample strength.For samples without β-quenching treatment,elongation and bending performance exhibit upward trends,showing a fundamentally positive correlation between bending formability and elongation.When TA5 ingots undergo hot breakdown rolling in the single-phase region to 9 mm,followed by 940℃ rolling to 5 mm,then warm rolling at 550℃ from 5 mm to 4 mm,and finally 650℃ annealing for 40minutes with air cooling,uniform fine equiaxed microstructures can be achieved.关键词
