Abstract:
MicroSim Bars® and PhasTranSim® are instruments devised to assist research and development engineers in designing steel products with particular metallurgical and mechanical properties. MicroSim Bars® serves as a simulation tool that calculates the progression of austenite during the hot rolling of steel bars, using variables such as chemical composition, temperature, and deformation parameters. It forecasts modifications in the steel's microstructure throughout the rolling process, pivotal for determining the ultimate properties of the product. Conversely, PhasTranSim® is a computational tool focused on the phase shifts occurring in steels post hot rolling, encompassing the transformation from austenite to ferrite, pearlite, bainite, or M/A constituents. It assists research and development engineers in determining how changes in process conditions impact the steel's microstructure and mechanical/metallurgical attributes. These tools facilitate the efficient development of steel products with desired features, potentially leading to cost reductions. The aim of this study was to assess microstructural changes in SAE1045 steel wire rod due to some modifications in the rolling process and alloy design, as well as to perform a comparison between measured metallurgical properties values and those calculated using the models. These results were used to check the accurateness of the models embedded in MicroSim Bars® and PhasTranSim®.
