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.

为了质量控制的目的，在DFG优先计划1204中开发了一种用于微观结构分析（SMA）的快速方法。所开发的方法进行了测试，为选定的钢种使用连续的过程链杆生产。首先，在实验室规模中测试该方法。该方法是基于X射线衍射图（XRD）的分析。在此，变形状态与SMA、光学显微镜以及力学测试的结果一起存储在数据库中并关联。在这些数据库的基础上，可以快速将给定材料的微观结构特征与SMA相关联。在实际应用中验证所开发的方法，并根据工业要求进行进一步开发，是该转移项目的目标。此外，SMA-性能-微观结构-因此，计划研究的重点是具有更复杂微观结构的钢种及其在整个轧制工艺链中的发展，在SMA数据库的研究中开发的模型将成为工艺链中微观结构演变模拟的基础，也是质量管理任务检查或工艺优化的工具。
