Combined online microstructure sensor and model for better control of hot rolling conditions and final products Properties (phase 2) (MicroControl-PLUS) : final report

This project aims at providing improvements to a first Laser Ultrasonic System (LUS) which was assembled and tested during a previous RFCS MicroControl project. These target improvements include several aspects: robustness of the LUS, to validate with on-line trials at AM EisenHuettenStadt's hot rolling mill, including exhaustive safety aspects; additional scientific knowledge on the links between ultrasonic signals and microstructural features of interest, with the development of a software tool to derive metallurgical quantities of interest such as grain size or austenite/ferrite ratio; improvement of existing metallurgical models to provide another approach for assessing the metallurgical quantities of interest and compare them to LUS results. The project's targets and essential findings are reviewed first on a condensed WP per WP basis, and synthetized in a final conclusion section.
