The processing-microstructure-property relationships in steels continue to present challenges to researchers because of the complexity of phase transformation reactions and the wide spectrum of microstructures and properties achievable. This major two-volume work summarises the current state of research on phase transformations in steels and its implications for the emergence of new steels with enhanced engineering properties. Volume 1 reviews fundamentals and diffusion-controlled phase transformations. After a historical overview, chapters in part one discuss fundamental principles of thermodynamics, diffusion and kinetics as well as phase boundary interfaces. Chapters in part two go on to consider ferrite formation, proeutectoid ferrite and cementite transformations, pearlite formation and massive austenite-ferrite phase transformations. Part three discusses the mechanisms of bainite transformations, including carbide-containing and carbide-free bainite. The final part of the book considers additional driving forces for transformation including nucleation and growth during austenite-to-ferrite phase transformations, dynamic strain-induced ferrite transformations (DIST) as well as the effects of magnetic fields and heating rates. With its distinguished editors and distinguished international team of contributors, the two volumes of Phase transformations in steels is a standard reference for all those researching the properties of steel and developing new steels in such areas as automotive engineering, oil and gas and energy production. Discusses the fundamental principles of thermodynamics, diffusion and kinetics Considers various transformations, including ferrite formation, proeutectoid ferrite and cementite transformations Considers additional driving forces for transformation including nucleation and growth during austenite-to-ferrite phase transformations

In the decade since the first edition of this popular text was published, the metallurgical field has undergone rapid developments in many sectors. Nonetheless, the underlying principles governing these developments remain the same. A textbook that presents these advances within the context of the fundamentals is greatly needed by instructors in the field Phase Transformations in Metals and Alloys, Second Edition maintains the simplicity that undergraduate instructors and students have come to appreciate while updating and expanding coverage of recently developed methods and materials. The book is effectively divided into two parts. The beginning chapters contain the background material necessary for understanding phase transformations - thermodynamics, kinetics, diffusion theory and the structure and properties of interfaces. The following chapters deal with specific transformations - solidification, diffusional transformation in solids and diffusionless transformation. Case studies of engineering alloys are incorporated to provide a link between theory and practice. New additions include an extended list of further reading at the end of each chapter and a section containing complete solutions to all exercises in the book Designed for final year undergraduate and postgraduate students of metallurgy, materials science, or engineering materials, this is an ideal textbook for both students and instructors.

Dilatometry is widely used in the investigation of phase transformation in steels, not only by research laboratories but also by most steel makers. Its application includes the determination of CCT and TTT diagrams, and more generally the investigation of phase transformation kinetics under controlled temperature conditions. A basic and often undiscussed assumption in the exploitation of dilatation measurements as a function of temperature is that of a constant and uniform temperature distribution in the specimen, and of a homogeneous material. In the present paper, various issues encountered with a widely used quenching dilatometer were discussed, including longitudinal temperature gradients, deformation anisotropy, or vacuum evaporation of some chemical species.

In this study, contemporary steel research is revealing new processing avenues to tailor microstructure and properties that, until recently, were only imaginable. Much of the technological versatility facilitating this development is provided by the understanding and utilization of the complex phase transformation sequences available in ferrous alloys. Today we have the opportunity to explore the diverse phenomena displayed by steels with specialized analytical and experimental tools. Advances in multi-scale characterization techniques provide a fresh perspective into microstructural relationships at the macro- and micro-scale, enabling a fundamental understanding of the role of phase transformations during processing and subsequent deformation.

Quenching and tempering are common processes used in the manufacture of steel components. The development of simulation tools for quenching is critical for improving process performance by minimizing component distortion and maximizing service life. While modeling of quenching has received considerable attention, there has not been much work on similar tools for tempering. This paper presents an efficient simulation tool to predict microstructure, temperature, and stress evolution, and is applicable to both quenching and tempering processes. This method takes into account the temperature dependence of material properties, transformation strains, latent heats of transformation, and transformation plasticity. Furthermore, three different micromechanical approaches are implemented and studied to simulate steel as a multiphase constitutive material: the average property model, the Voigt model, and the Reuss model. These models assume that the properties of a unit volume of material can be derived, respectively, by applying the linear rule of mixtures to the material properties of its constituent phases, by assuming that all constituent phases have the same strain field, and by assuming that all constituent phases have the same stress field. The model predicts the microstructure, stress, and distortion in the heat treated component. The simulation model is implemented within the framework of the ABAQUS finite element package by taking advantage of its advanced features to incorporate user defined material properties. Given that the material properties are strongly dependent on carbon content, the simulation method is tested using experiments with modified 4320 steel plates that were carburized on one side to amplify distortion when quenched, due to martensitic phase transformation. Distorted shapes are measured and compared to model predictions for both quenching and tempering. The detailed comparisons provide confidence in the model as well as suggestions for improvement.
