研究SAF 2205双相不锈钢冷轧退火板的冲压特性以及冷轧和退火织构对其冲压性能的影响.实验钢冷轧退火板表现出较差的深冲性能和明显的45°制耳,其r平均值和Δr值分别为0.7和-0.27,这主要与其在冷轧及退火后形成的织构有关.ODF图显示,退火后SAF 2205双相不锈钢中铁素体相未形成γ纤维再结晶织构,仍然为分散的α纤维织构.实验钢中铁素体相的织构强度明显高于奥氏体相,其对钢板成形性的影响更显著,即其各种〈110〉退火织构组分均不利于实验钢r平均值的提高,并且使得Δr<0.此外,奥氏体相的{110}〈001〉织构也对钢板成形性能产生一定程度的影响.
The stamping properties of SAF 2205 cold-rolled annealed sheets and the effect of cold-rolled and annealed textures on the stamping properties were studied.The cold-rolled annealed sheets of the experimental steels showed poorer deep-drawing properties and apparent 45 ° ear-making, The values of r and Δr were 0.7 and -0.27, respectively, which were mainly related to their texture after cold rolling and annealing.ODF showed that the ferrite phase of SAF 2205 duplex stainless steel did not form recrystallized γ fiber after annealing Structure is still dispersed α fiber texture.The texture strength of the ferrite phase in the experimental steel is significantly higher than the austenite phase, the impact on the formability of the steel plate is more significant, that is, the various <110> annealing texture group Points are not conducive to the experimental steel r average increase, and makes the Δr <0. In addition, the austenite phase {110} <001> texture also has a certain degree of steel forming performance.
