Book excerpt: This project aimed at improving cooling performances in cold rolling to make better lubricant properties in order to limit interaction between cooling and mill vibrations and to optimise selective cooling for flatness control. Tests of new cooling techniques (combination of different types or arrangements of nozzles, high turbulence cooling techniques) have been derived in design procedures and practical recommendations to improve cold mills productivity, product quality and water usage. When a lower exit strip temperature and/or a decrease of sensitivity to mill vibrations are required without designing completely new headers on an existing mill, a solution consists in optimising interstand strip cooling through the use of two coolant temperature circuits (one hot and one cold) in combination with drying ramps in last mill interstands to limit perturbation of lubrication by cooling.^When a decrease of water usage is required while maintaining a good cooling capacity, it is recommended to design new headers to use full cone nozzles for interstands strip cooling and new headers for the use of small roll cooling nozzles: the benefit in terms of flow rates (so water usage) may be more than 30 % water usage decrease in comparison to mills with normal to high flow rates. The High Turbulence Roll Cooling solution, alternative to nozzles-based cooling techniques, is a promising technique that should avoid perturbation of the lubrication system by cooling while working at a very low pressure (saving of energy). A new algorithm of selective cooling for exit strip flatness has been developed that determines automatically the required number of nozzles opened to maintain a good flatness. This new control strategy contributes to having an optimum efficiency of selective cooling whatever rolling conditions.^Different types of models have been developed and further used to design the above new cooling configurations and to deeply understand what makes a cooling configuration or technique efficient. The expected benefits for the European steel industry are the possibility to achieve higher rolling speeds and reductions, to decrease oil consumption and oil cost, and to reduce water consumption and recycled coolant quantities (positive environmental aspect).

Book excerpt: The microstructures of both martensite and bainite, although sharing some common features, depict a plethora of subtle differences that made them unique when studied in further detail. Tailoring the final properties of a microstructure based on one or the other as well as in combination with others and exploring more sophisticated concepts, such as Q&P and nanostructured bainite, are the topics which are the focus of research around the world. In understanding the key microstructural parameters controlling the final properties as well as definition of adequate process parameters to attain the desired microstructures requires that a proper understanding of the mechanism ruling their transformation and a detailed characterization first be acheived. The development of new and powerful scientific techniques and equipment (EBSD, APT, HRTEM, etc.) allow us to gain fundamental insights that help to establish some of the principles by which those microstructures are known. The developments accompanying such findings lead to further developments and intensive research providing the required metallurgical support.

Book excerpt: Thermomechanical Processing of High-Strength Low-Alloy Steels considers some advanced techniques and metallurgical bases for controlled-rolling. This book contains 12 chapters. In Chapter 1, the purpose of thermomechanical processing and historical survey is described, while in Chapter 2, the kinetics of phase transformations and refinement of grain size in steels are elaborated. The techniques and metallurgical bases for controlled-rolling in the recrystallization, non-recrystallization, and (? + y) regions are reviewed in Chapters 3 to 5. Chapters 6 and 7 discuss the deformation resistance during hot-rolling and restoration processes. The phase transformations during cooling following hot-rolling are mentioned in Chapter 8, followed by a summarization of the effects of alloying elements in Chapter 9. Chapters 10 and 11 deal with the mechanical properties of controlled-rolled steel and prediction and control of microstructure and properties by thermomechanical processes. The problems faced and possibilities for future developments are stated in the last chapter. This publication is recommended for physicists, metallurgists, and researchers concerned with controlled-rolling, including non-specialists who have some knowledge of metallurgy.

Gear Materials, Properties, and Manufacture is intended for gear metallurgists and materials specialists, manufacturing engineers, lubrication technologists, and analysts concerned with gear failures who seek a better understanding of gear performance and gear life. This volume complements other gear texts that emphasize the design, geometry, and theory of gears. The coverage begins with an overview of the various types of gears used, important gear terminology, applied stresses and strength requirements associated with gears, and lubrication and wear. This is followed by in-depth treatment of metallic (ferrous and nonferrous alloys) and plastic gear materials. Emphasis is on the properties of carburized steels, the material of choice for high-performance power transmission gearing.

Book excerpt: This is the third edition of the book, much expanded to include and incorporate important developments in the subject over the last fifteen years. The book represents a comprehensive treatise on all aspects of the bainite transformation, from the choreography of atoms during the phase change to length scales that are typical of engineering applications. The alloy design that emerges from this explains the role of solute additions, and the pernicious effects of impurities such as hydrogen. The picture presented is self-consistent and therefore is able to guide the reader on the exploitation of theory to the design of some of the most exciting steels, including the world’s first bulk nanostructured metal.
