This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The goal of this research was to develop a mechanical property prediction model using machine learning applied at the hot rolling processing stage for microalloyed steel strip produced at the Algoma steel mill located in Ontario, Canada. A neural network model was created to provide predictions of the lower yield strength (LYS) and ultimate tensile strength (UTS). The as-received dataset for prediction of mechanical properties comprised chemical composition and hot rolling processing parameters of temperature, roll speed, roll gap, and strip speed. The model was able to predict the LYS of 88% of the test data with an error of less than or equal to ± 5% and the UTS of 99% of the test data within the same error range. The model results were then used to determine the relative influence of each element in the chemical composition and each hot rolling process parameter on the LYS and UTS. Important features for the determination of strength were the strain at the roughing stand, strain at finishing stand number 2, nitrogen (for LYS) and niobium (UTS) concentrations, and the bar entry temperature. The importance of these features can be rationalized on the basis of physical metallurgy principles based on the effect of hot deformation on the formation of Nb(C, N) precipitates. Precipitation start time is expected to be influenced by the grain size of recrystallized austenite inherited from strain at the roughing stand. Depending on the precipitation start time, strain accumulation in austenite begins as early as after finishing stand number 2 and ultimately influences UTS and LYS by the mechanism of grain refinement. The bar entry temperature will influence the temperature profile through the entire hot rolling stage. A potential application of the model is to reduce the variation of mechanical properties. To demonstrate a possible application of this model, it was shown that variations in chemical composition observed in the as-received dataset will lead to mechanical property variations, but these can be countered by modifying the hot rolling process details, thus reducing mechanical property variations"--

Available in PDF, EPUB and Kindle. Book excerpt: This book gathers a collection of papers summarizing some of the latest developments in the thermomechanical processing of steels. The replacement of conventional rolling plus post-rolling heat treatments by integrated controlled forming and cooling strategies implies important reductions in energy consumption, increases in productivity and more compact facilities in the steel industry. The metallurgical challenges that this integration implies, though, are relevant and impressive developments that have been achieved over the last 40 years. The frequency of the development of new steel grades and processing technologies devoted to thermomechanically processed products is increasing, and their implementation is being expended to higher value added products and applications. In addition to the metallurgical peculiarities and relationships between chemical composition, process and final properties, the relevance impact of advanced characterization techniques and innovative modelling strategies provides new tools to achieve the further deployment of the TMCP technologies. The contents of the book cover low carbon microalloyed grades, ferritic stainless steels and Fe–Al–Cr alloys, medium-Mn steels, and medium carbon grades. Authors of the chapters of this "Thermomechanical Processing of Steels" book represent some of the most relevant research groups from both the steel industry and academia.

Available in PDF, EPUB and Kindle. Book excerpt: A metallurgical model allows the prediction of the mechanical properties and microstructural characteristics of hot rolled steel strips immediately after production. Data collection was carried out in three different hot strip mills for the StripCam model validation. A physically based model, CamModel, developed by Corus, has been evaluated as an alternative to the StripCam model for predicting the microstructures of hot rolled strips. Both models generally produce very similar results. Corus has tried to determine the austenite grain size after reheating. The deviations found in the austenite grain size TKS model have no significant impact on the final results. New equations for the phase transformation kinetics model of CRM StripCam have been recalculated. Concerning the model developed by Arcelor Research, the focus was on the growth rate of ferrite assuming a mix mode mechanism: diffusion of carbon in the austenite and intrinsic mobility of the interface. A microstructural-based model for predicting the mechanical properties in ferrite-pearlite steels was developed by Arcelor Research. A mixture law without a fitting parameter is also proposed to determine the flow curve of a ferrite-pearlite microstructure. A major topic of StripCam improvement concerned the bainite mechanical property model. TKS has obtained new equations for a better prediction of the mechanical properties of annealed and of isothermal formed bainite. A more accurate TS equation was also adjusted by CRM. Neural models are able to predict accurately the mechanical properties if they have been properly trained with an adequate dataset. The final models have been extensively validated, showing a prediction error usually within acceptable tolerance ranges.

Available in PDF, EPUB and Kindle. Book excerpt: Advanced high strength steels (AHSSs) for auto-making are primarily produced by rolling, plus heat treatment technologies if necessary. However, due to the metallurgical complexity of AHSSs, it is impossible to roll all of the AHSS grades in a rolling mill with the same rolling technology. Each of AHSSs has unique applications in vehicles, and specified rolling technologies are required to produce high quality AHSS products where they might be the best employed to meet performance demands of the automotive parts. Such background has prompted the publication of this scholarly book in the area of rolling of AHSSs with a purpose of providing readers with a valuable technical document that can be used in the research and development of AHSSs for automotive and other manufacturing industries. With contributors from USA, Germany, Poland, Italy, Spain, Austria, Australia, China, India and Iran, the book highlights the latest advances in rolling technologies of AHSSs. It focuses on the theory, simulation and practice of the rolling of AHSSs: The book introduces the history, types and advances of AHSSs and their processes; proposes new theory that is applicable to the rolling of AHSSs, presents mathematical and numerical modelling of AHSSs in rolling; covers thermomechanical processing technologies of AHSSs; provides case studies on the rolling practice of the most popular AHSSs and includes other rolling-related technologies of AHSSs. The book will be useful for both theoretical and applied research aimed at AHSSs rolling technologies, and will be a scientific and valuable literature for the metallurgists, engineers, materials scientists, academics and graduate students who are studying and working with AHSSs and their rolling technologies worldwide.
