| 摘 要： | 研究了0～0.21%Ti和0～0.29%Nb对Cr18钢(%:0.008～0.009C、17.48～17.57Cr)的组织、再结晶织构、力学性能和成形性能的影响。结果表明,Nb稳定化退火冷轧板的晶粒较Ti稳定化退火冷轧板细小;Ti-Nb稳定化的冷轧板{111}〈112〉取向密度最大、Ti稳定化冷轧板次之,Nb稳定化冷轧板最小;Ti、Nb、Ti-Nb稳定化退火冷轧板应变硬化指数n值分别为1.55、1.12和1.48,因此Ti和Ti-Nb稳定化退火冷轧板的成形性良好。

| Abstract: | Effect of 0 ~ 0. 21 % Ti and 0 ~0. 29% Nb on structure, recrystallization texture, mechanical properties and formabilitv of ultra-low carbon ferrite stainless steel Cr18 (% ： 0. 008 ~0. 009C, 17. 48 ~ 17. 57Cr) has been studied. Results show that the grain size of annealed cold rolled sheet of Nb stabilized steel is finer than that of Ti stabilized steel; the {111} < 112 > orientation density of cold-rolled sheet by Ti-Nb stabilization is maximum, that by Ti stabilization is second and that by Nb stabilization is minimum； the strain-hardening exponent n- value of annealed cold-rolled sheet by Ti, Nb and Ti-Nb stabilization is respectively 1. 55, 1. 12 and 1.48, therefore the formability of annealed cold-rolled sheet by Ti and Ti-Nb stabilization is excellent. |
