9. An Integrated Modelling Concept Based upon Three-Dimensional Models

The chapter presents sample physical and computer simulation results, conducted based on the modelling concept utilising full three-dimensional solutions. In the first part of the chapter, the initial results were presented, verifying the developed three-dimensional solutions spanning high-temperature processes for the macro scale: heating/melting/solidification as well as deformation. In the subsequent part, results of microstructure tests were presented, indicating high variability of the achievable cooling rates in the analysed medium volume. The research is supplemented by the developed concept method of estimation of the microstructure based on special “high-temperature” CCT diagrams. The final part presents results of experimental trials concerning verification of the developed grain growth model for the micro scale. The developed model is a unique one, spanning in a comprehensive manner the growth of grain in an integrated heating-melting-cooling process in the Gleeble 3800 simulator equipment.
