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: The Special Issue ‘Physical Metallurgy of High Manganese Steels’ addresses the highly fascinating class of manganese-alloyed steels with manganese contents well above 3 mass%. The book gathers manuscripts from internationally recognized researchers with stimulating new ideas and original results. It consists of fifteen original research papers. Seven contributions focus on steels with manganese contents above 12 mass%. These contributions cover fundamental aspects of process-microstrcuture-properties relationships with processes ranging from cold and warm rolling over deep rolling to heat treatment. Novel findings regarding the fatigue and fracture behavior, deformation mechanisms, and computer-aided design are presented. Additionally, the Special Issue also reflects the current trend of reduced Mn content (3-12 mass%) in advanced high strength steels (AHSS). Eight contributions were dedicated to these alloys, which are often referred to as 3rd generation AHSS, medium manganese steels or quenching and partitioning (Q&P/Q+P) steels. The interplay between advanced processing, mainly novel annealing variants, and microstructure evolution has been addressed using computational and experimental approaches. A deeper understanding of strain-rate sensitivity, hydrogen embrittlement, phase transformations, and the consequences for the materials’ properties has been developed. Hence, the topics included are manifold, fundamental-science oriented and, at the same time, relevant to industrial application.

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.

Download or read book Modeling of the Microstructure and Mechanical Properties of Steels During Thermomechanical Processing written by Y.-W. Cheng and published by . This book was released on 1997 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Models have been developed for the microstructural changes in C-Mn, vanadium-treated and eutectoid steels during thermomechanical processing. They relate processing parameters, such as strain, strain rate, and temperature to microstructural features, such as volume fraction of the recrystallized material and austenite grain size, with emphasis on the effect of microstructural changes on the mechanical properties of the final product. Model-predicted mechanical properties were compared with values measured in laboratory and industrial experiments. The models gave an accurate, quantitative characterization of the plates, rods, and rails subjected to rolling processes. The results of this study provide a basis for future optimization of the chemical composition and processing of steels.

Available in PDF, EPUB and Kindle. Book excerpt: "Developing high strength steels has received increasing attention in steel industry, in order to meet the body-in-white weight reduction strategies pursued by the automotive industry for fuel economy and vehicle safety. In this context, medium manganese (Mn) steels containing 3 to 12 wt.% Mn are one of the strong candidates for the so-called third-generation advanced high-strength steels (AHSS), due to the superior mechanical properties exceeding the first-generation AHSS and the potentially lower cost compared to the high Mn second-generation AHSS. The ultrafine grain size and high fraction of retained austenite, adjustable to various TRIP (transformation-induced plasticity) and/or TWIP (twinning-induced plasticity) effects, constitute the key advantages of this group of steels. This thesis aims to develop a better understanding of the processing-microstructure-property relationship of medium Mn steels with Al and Si additions. Four experimental steels with compositions of Fe-0.2C-(7~10)Mn-3Al-(0~3)Si (in wt.%) were designed and examined. The phase transformation behavior, with respect to austenite formation and decomposition, of two hot rolled samples with 3 wt.% Al and 3 wt.% Si during intercritical annealing was firstly investigated to develop a better understanding of microstructural control for such steels. The microstructure of the leaner alloy with 7 wt.% Mn was substantially influenced by the annealing temperature, whereas the richer variant 10 wt.% Mn steel exhibited a stable ferrite-austenite duplex microstructure containing a fixed amount of retained austenite, which was found to be independent of the variations of annealing temperature. From these results, controlled annealing was performed for these two hot rolled samples, followed by a further processing by subjecting them to cold rolling and examining the microstructural evolution during cold rolling. Strain partitioning, between austenite and ferrite, and deformation twinning of austenite were found to critically influence the cold rollability of the two steels. Finally, the deformation and fracture mechanisms of the cold rolled and intercritical annealed medium Mn steels were studied, with particular emphasis on the effect of different Si additions (0~3 wt.%). Results showed that the mechanical property of the steels critically depended on the austenite fraction, TRIP and TWIP effect activated in austenite, as well as the strain partitioning between austenite and ferrite during deformation. The fracture mechanisms altered with different Si levels, which can change from dimpled-type fracture driven by void formation, mainly at the ferrite/strain-induced [alpha]′-martensite interfaces, to a combined dimple and cleavage/quasi- cleavage fracture, which was related to the brittle [delta]-ferrite in high Si alloys. The work also revealed a strong correlation between strain-induced martensite formation and the serrated plastic flow phenomenon associated with the Portevin-Le Chatelier effect (PLC) effect. Discontinuous behavior of strain-induced transformation was observed, which was due to the localized martensite formation within the PLC bands nucleating intermittently and propagating continuously during tensile straining.
