Effects of Finishing Annealing Temperature on Deformation Texture and Mechanical Properties of Zr-4 Zirconium Alloy Tube AITranslate
Abstract AITranslate
The effects of annealing temperature on metallographic microstructure,deformation texture,contractile strain ratio（CSR）and Kearns coefficient Frof the finished Zr-4 zirconium alloy were studied.When the finished tube is annealed for stress relief at 450~500 ℃,the tube is in the recovery stage,and this process can not weaken deformation texture formed by crystal surface sliding due to metal deformation.Compared with the rolled tube,CSR value of the annealed tube at 450~500 ℃ has no significant change,and its Frvalue slightly increases with the increase of annealing temperature.At the annealing temperature of 500~530℃,the zirconium alloy tube is in the transition zone between the recovery stage and the recrystallization stage,and most of deformation texture is transformed into annealed texture,resulting in a sharp increase of Frvalue and CSR value.At the annealing temperature of 530~560 ℃,the zirconium alloy tube is in the stage of recrystallization,its microstructure is of equiaxed recrystallized morphology,and the original deformation texture has basically been completely replaced by annealed texture.However,the tube in the stage has not reached complete recrystallization,resulting in a slight increase of Frvalue and CSR value.
