of σb is close to the value of σ0.2 in every route, i.e., the yield ratio (σ0.2/σb) is high, which may result in difficulty in cold-deformation. 3.2 Microstructural evolution Fig.2 shows the optical... of the refined and dispersed α+β phase on the basis of high dislocation density by pre-deformation below recrystallization temperature. The tensile strength decreases with the increase of pre......
for the hot-rolling and the thickness of plate was 5.5 mm after cogging. To achieve large deformation in the cold-rolling, the best parameters for softening annealing must be decided. Adopted 450, 500, 550 ℃ for 0.5, 1, and 1.5 h and went on cold-rolling and analyzing. The thickness of strip was 0.5 mm after the first cold-rolling with 90.9% deformation. The second annealing went on at 550......
; 文献标志码:A 文章编号:1672-7207(2014)05-1437-06 Influence of cold deformation and annealing on microstructure...: The influence of cold deformation and annealing on microstructure and properties of Ti50Ni45Cu5(at%) alloy were investigated. The results show that the martensite plate becomes smaller and the tensile......
