研究了初始组织对409L铁素体不锈钢组织和织构的影响。将冷轧和退火工艺引入到了等轴晶和全柱状晶铸带中。结果表明,全等轴晶铸带经冷轧后以较强的α纤维织构和γ纤维织构,全柱状晶铸带经冷轧后以较强的α纤维织构和较差的γ纤维为特征。退火工艺后,与全柱状晶铸带经冷轧退火后相比,全等轴晶铸带经冷轧后组织更加细小、均匀,全等轴晶试样经冷轧后γ纤维织构相比没有处理的更强。
The effect of initial microstructure on microstructure and texture of 409L ferritic stainless steel was studied. The cold rolling and annealing process is introduced into the equiaxed and full columnar crystal casting belt. The results show that the congruent axis crystal cast strip is strongly α fiber texture and γ fiber texture after cold rolling. The full columnar crystal strip is cold rolled with stronger α fiber texture and poorer γ fiber For the characteristics. After the annealing process, compared with the full columnar crystal strip after cold rolling annealing, the congruent axis crystal cast strip by cold rolling after the organization is more fine, uniform, congruent axis of the sample after cold-rolled γ fiber texture compared to Not deal with stronger.
