摘　　要：通过金相和EBSD等技术,观察了不同热轧终轧温度对00Cr21 Mo1铁素体不锈钢热轧态、热轧退火态和冷轧退火态织构变化的影响情况,并分析讨论了较高终轧温度下铁素体不锈钢00Cr21 Mo1塑性应变比(Rm)较低的原因。结果表明,较低的终轧温度下,00Cr21 Mo1热轧态组织形变带宽度较小,受轧辊切应变而形成的{110}<001>、{110}<112>、{4 4 11}<11 11 8>织构组分强度较小,且均匀、分散,最终冷轧退火态以{111}面织构为主,塑性应变比较高。The effect of FDT（finishing delivery temperature） on the changs in texture of ferritic stainless steel 00Cr21Mo1 state of hot-rolled,hot-rolled annealed,cold-rolled annealed was investigated by using EBSD and metallographical technology.The reason why Rm was lower with a higher FDT was discussed.The result showed that the intensity of {110}〈001〉 、{110}〈112〉、{4 4 11}〈11 11 8〉caused by shearing deformation during hot rolling was lower and its distribution was even and scattered.The R（m） was higher and most of the texture is {111} in the cold-rolled annealed state.
