摘要: 

以一种含W和稀土Ce的444型耐热铁素体不锈钢19Cr2Mo1W为材料,利用XRD测试分析、EBSD取向成像技术、粗糙度测量和成形性测试等手段,研究了该铁素体不锈钢热轧板不同退火工艺对其冷轧退火板的微观组织、织构演变以及成形性能的影响。结果表明,尽管采用了不同退火温度的热轧板退火工艺,但是热轧退火板的织构特征在一定程度上均会遗传至冷轧板;热轧退火板中增强的{223}<11ˉ0>和{111}<01ˉ1>织构组分存在,有利于增加冷轧退火板中γ纤维织构的强度。冷轧板中{001}<11ˉ0>~{115}<11ˉ0>纤维织构组分越强,退火后γ纤维织构偏离理想程度越大;适当提高热轧板退火温度可以有效减弱冷轧板中有害的{001}<11ˉ0>~{115}<11ˉ0>组分。提高热轧板退火温度,可以显著减轻甚至彻底消除热轧退火板中的带状组织、提高冷轧退火板的组织均匀性和γ纤维织构强度,有利于成形性能的提高。

Abstract

Low-cost ferritic stainless steels with excellent oxidation resistance and anti-corrosion ability are widely used in the fields of household appliances, hardware decoration, architectural structures, fuel cells and automobile exhaust systems. In order to achieve good formability of the ferritic stainless steel, the annealing process of hot-rolled sheet is crucial. As a newly developed 444-type heat-resistant ferritic stainless steel containing W and Ce, however, the influence of hot band annealing process of 19Cr2Mo1W ferritic stainless steel on its formability is not clear and need to have a deep understanding. In this work, the effect of annealing temperature of hot band on the microstructure, texture and formability of this steel was studied by means of XRD, EBSD, roughness measurement and formability test. The results indicated that although annealing processes were carried out at different temperatures after hot rolling, the characteristic of texture in the hot-rolled and annealed sheet was inherited to the cold-rolled sheet to some extent. The increased intensities of {223}<11ˉ0> and {111}<01ˉ1> texture components in the hot-rolled and annealed sheet were beneficial to improvement of the γ-fiber texture in the cold-rolled and annealed sheet. The extent of deviation from γ-fiber texture in the cold-rolled and annealed sheet was increased with increasing the intensities of {001}<11ˉ0>~{115}<11ˉ0> texture components in the cold-rolled sheet. An increased annealing temperature of the hot-rolled sheet could effectively weaken the intensities of {001}<11ˉ0>~{115}<11ˉ0> texture components in the cold-rolled sheet. In addition, the banded microstructures in the hot-rolled and annealed sheet were significantly reduced by increasing annealing temperature of the hot-rolled sheet, which improved the microstructure uniformity and formability of the cold-rolled and annealed sheet.
