冷轧430铁 素体不锈钢 经过 略低于 再结晶温度 长时间 保温，再高温 再结晶 退火 后 能获 得高份额 的γ-纤维织构。这种 高份额的 γ-纤维织构的 获得 主要归因于 大冷轧形变量 和 形变组织的 充分回复。随着 保温时间的 延长，其 织构强度 逐渐增加，样品的 织构类型 基本没有变化。这种 热处理制度 处理的 样品 与 直接退火的 样品相比 有着 更高的 γ-纤维织构 和 更少的{211}<011>织构。但 两种 退火制度 都难以 去除 形变储能 较低的 {100}<011>旋转立方织构 晶粒。
Cold-rolled 430 ferritic stainless steel is firstly subjected to long time of thermal insulation at temperature which is slightly lower than recrystallization temperature, and then subjected to high temperature recrystallization annealing before obtaining high share of γ-fiber texture. The reason for obtaining such high share of γ-fiber texture is mainly due to large cold rolling deformation and full response to deformed microstructure. As the extending of holding time, the texture intensity gradually increase while the texture types of sample remain roughly unchanged. Compared with sample under direct annealing, sample under such heat-treatment mechanism has higher γ-fiber texture and less {211}<011> texture. However, both annealing mechanisms can hardly remove {100}<011> rotating cube texture grain of lower deformation stored energy. |
