薄带连铸Cr17铁素体不锈钢的织构演变

以具有不同初始组织的Cr17铁素体不锈钢双辊连铸薄带为实验材料,分别进行相同的冷轧及退火处理,对织构演变进行了对比研究.结果表明:织构演变与薄带的初始组织、织构密切相关.柱状晶薄带具有显著的(001)//ND织构,等轴晶薄带则具有微弱的随机织构;两者经冷轧后都形成了较温和的α纤维织构及较均匀的γ纤维织构,但是,后者的α...

Texture Evolution of Cr17 Ferritic Stainless Steel Produced by Thin Strip Casting

The Cr17 ferritic stainless steel specimens of different initial microstructures were produced by thin strip casting and investigated comparatively for their texture evolution via the same cold rolling and annealing processes.The results showed that the texture evolution closely relates to the initial microstructure and texture of the cast strips.The cast strip with columnar crystals presents clearly the 〈001〉∥ND fiber texture,while the cast strip with equiaxed crystals presents the weak and nearly random texture.Then,after cold rolling,the mild α-fiber texture and homogeneous γ-fiber texture form in both the two types of cast strips,among which the latter shows much stronger α-fiber and γ-fiber textures than the former.After the recrystallization annealing,both the two types of cast strips form the homogeneous γ-fiber recrystallization texture which is clearly stronger in the latter than in the former.
