Relationships between Spring-back and Microstructure of Ti-15V-3Cr-3Sn-3Al Titanium Alloy Sheet during Bending Process

摘要：

　　Evolutions of microstructure,micro- hardness in the central deformation area and spring-back,were studied in different bending conditions of Ti-15V-3Cr-3Sn-3Al titanium alloy sheet.The results show that,with the increase of bending deformation,i.e.increase of bending angle or decrease of bending radius,the grain area,the grain feret diameter ratio and micro-hardness in the central deformation area all show nearly linear growth trends.The spring-back angle has no clearly correlation with the degree of bending deformation.While the spring-back rate correlates positively with the length of deformation-affected zone,which can reflect the characteristics of bending deformation more intuitively than that of spring-back angle.
