研究了添加Ti、Nb对超低碳Cr18铁素体不锈钢冷轧板再结晶织构的影响。试验结果表明,Nb单稳定化和Ti、Nb双稳定化的冷轧板试样在850℃下,随退火保温时间的延长,{111}面织构取向密度增加,而Ti单稳定的冷轧板在退火2min时{111}面织构取向密度值达到最大,然后随保温时间延长{111}面织构密度下降。Ti、Nb双稳定化的冷轧板经退火360s后得到最大的{111}<112>织构取向密度强度,Nb单稳定化Cr18不锈钢冷轧板再结晶织构{111}取向密度低于其它两种钢。
The effects of adding Ti and Nb on the recrystallization texture of ultra-low carbon Cr18 ferritic stainless steel sheet were studied. The experimental results show that the tensile strength of {111} plane increases with the increase of annealing time at 850 ℃ for Nb single-stabilized and Ti, Nb bistable cold-rolled samples. However, the Ti single stable cold rolled After annealing for 2 min, the texture orientation density of {111} plane reached the maximum, and then the texture density of {111} plane decreased with the increase of holding time. Ti, Nb bistable cold-rolled sheet after annealing for 360s to obtain the largest {111} <112> texture orientation density strength, Nb single-stabilized Cr18 stainless steel cold rolled sheet recrystallization texture {111} orientation density lower than the other Two kinds of steel.
