CSP CDCM BA流程钢板组织性能演变规律

 通过低碳铝镇静钢CSP CDCM BA流程的工业试验，借助光学显微镜、X射线衍射仪和专用拉伸试验机等设备，测定了热轧、冷轧、退火和平整后钢板的组织、织构、力学性能和基本成形性能，并对其特征、演变规律及影响因素进行了分析，验证了退火平整板r值的变化与{111}/{100}的线性关系。结果表明，增加{111}和减少{100}织构组分对提高薄钢板成形性能同样重要。

Evolution Rules of Microstructure and Property of Sheets in CSP-CDCM-BA Process

Through industrial experiment on the whole process of CSP CDCM BA with low carbon Al killed steel, the microstructures, textures, mechanical properties and basic formability of the hot rolled, cold rolled, batch annealed, and temper leveled sheets are determined by means of instruments such as optical microscope, X ray diffraction instrument and special tension tester and so on. Their characteristics, evolution rules and influencing factors are primarily analyzed, too. Furthermore, the linear relationship between r value and ratio of {111}/{100} has been proved, which reveals that it will be same important to increase the component of {111} texture and to decrease the component of {100} texture.
