For the purpose of quality control a fast method for microstructural analysis (SMA) was developed within the DFG - priority program 1204. The method developed was tested for selected steel grades using a continuous process chain for rod production. First the method was tested in a laboratory scale. The method is based on the analysis of X-ray diffraction pattern (XRD). Herein the deformation state together with the results of SMA, optical microscopy as well as mechanical tests were stored and correlated in a data base. On the basis of these data base a fast correlation between microstructure characteristics and SMA for a given material is possible.A verification of the developed method in practical application and a further development in relation to industrial requirements is the goal of the transfer project.Additional, a further extension of the data base of SMA-property-microstructure-correlations to a wider spectrum of practical relevant materials is planned.Therefore the focus of the planned investigations is on steel grades with a more complex microstructure and its development during the whole process chain of rolling, rod drawing and spring production.Models developed within the investigations in the SMA-data base will be the foundation for a simulation of the microstructure evolution within the process chain as well as a tool for the quality management tasks inspection or process optimization.

为了进行质量控制，在DFG - 优先计划1204中开发了一种快速的微结构分析方法（SMA）。开发的方法使用连续的杆生产过程链测试了所选钢等级。首先，该方法在实验室范围内进行了测试。该方法基于X射线衍射模式（XRD）的分析。此处的变形状态以及SMA的结果，光学显微镜以及机械测试在数据库中存储并相关。根据这些数据的基础，可以为给定材料的微观结构特征与SMA之间的快速相关关系。对开发的方法的验证在实际应用中的验证以及与工业需求的进一步发展是转移项目的目标。在整个滚动，杆绘图和弹簧生产过程中，具有更复杂的微观结构及其开发的钢等级，SMA-DATA基础的研究中开发的模型将是模拟过程链中的微观结构演化的基础，以及用于质量管理任务检查或过程优化的工具。
