Finite element models (FEM) for hot rolling of plate have been developed and linked with metallurgical algorithms for the variation in austenite state and hence properties. One model has been further linked with metallurgical algorithms for transformation characteristics upon cooling after rolling, the results of which are in reasonable agreement with experiment. The in-house Prefect FEM has been developed for improved pre-processing and post-processing, and inhomogeneous stock. The commercial Abaqus FEM package has been adapted to suit hot rolling of plate, and it is this model which additionally includes the algorithms for phase transformation upon cooling. An experimental work programme has been performed for the assessment or derivation of the required metallurgical algorithms for phase transformation, and for validatory tests of the completed computer model. Experimental validation of the completed Abaqus model was performed. The combined finite element/microstructural evolution model 'FEMME', is considered suitable for semi-quantitative predictions of microstructure particularly for the development of optimized C-Mn steel plate rollings.
