Book Description
The perpetual flow of understanding between phase transformation that controls grain/microstructures and heat treatment which decides the size of grains/microstructures of steels is not well articulated in the perspective of undergraduate students. In Phase Transformations and Heat Treatments of Steels, theories of phase transformation have been used to obtain a desirable phase or combination of phases by performing appropriate heat treatment operations, leading to unification of both the concepts. Further, it includes special and critical heat treatment practices, case studies, local and in-service heat treatments, curative and preventive measures of heat treatment defects for several common and high-performance applications. Features: Presents fundamentals of phase transformation in steels Analyzes basics of phase transformation due to heat treatment of steel under various environmental conditions Explains application of heat treatment for different structural components Discusses heat treatment defects and detection Emphasizes heat treatment of special steels and in-situ heat treatment practices

Phase Transformations in Steels PDF Author: Elena Pereloma
Publisher: Elsevier
ISBN: 0857096109
Category : Technology & Engineering
Languages : en
Pages : 656

Book Description
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

Pages : 532

Book Description
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.

Pages : 348

Book Description
Heat Treatment Of Steels As An Art To Improve Their Service Performance Has Been Practised Ever Since It Started To Be Used As Tools And Weapons.However, The Scientific Basis Of Heat Treatment Of Steels Became More Apparent Only In The First Half Of This Century And Still Some Gaps Remain In Its Complete Understanding.Earlier Books On Heat Treatment Of Steels Mainly Emphasised The Art And The Empirically Arrived Principles Of Heat Treatment. In The Last Few Decades, Our Understanding Of Phase Transformations And Mechanical Behaviour Of Steels, And Consequently Of Heat Treatment Of Steels, Has Considerably Increased.In This Book On Principles Of Heat Treatment Of Steels The Emphasis Is On The Scientific Principles Behind The Various Heat Treatment Processes Of Steels. Though It Is Expected That The Reader Has Sufficient Background In Phase Transformations And Mechanical Behaviour Of Materials, First Few Chapters Review These Topics With Specific Reference To Steels. Basic Principles Of Various Heat Treatment Processes Of Steels Including Surface Hardening Processes, Are Then Covered In Sufficient Detail To Give A Good Overall Understanding Of These Processes. The Detail Engineering Aspects Are, However, Omitted. These Are Easily Available In Various Handbooks On Heat Treatment. The Book Also Covers Heat Treatment Of Tool Steels And Cast Irons.The Book Has Been Well Written And Can Be Used A Textbook On Heat Treatment For Undergraduate Students. It Is Also A Good Reference Book For Teachers And Researchers In This Area And Engineers In The Industry.

Book Description
This book provides a solid overview of the important metallurgical concepts related to the microstructures of irons and steels, and it provides detailed guidelines for the proper metallographic techniques used to reveal, capture, and understand microstructures. This book provides clearly written explanations of important concepts, and step-by-step instructions for equipment selection and use, microscopy techniques, specimen preparation, and etching. Dozens of concise and helpful “metallographic tips” are included in the chapters on laboratory practices and specimen preparation. The book features over 500 representative microstructures, with discussions of how the structures can be altered by heat treatment and other means. A handy index to these images is provided, so the book can also be used as an atlas of iron and steel microstructures.

Modeling martensitic phase transformation in dual phase steels based on a sharp interface theory

Modeling martensitic phase transformation in dual phase steels based on a sharp interface theory PDF Author: Ruck, Johannes
Publisher: KIT Scientific Publishing
ISBN: 3731510723
Category : Technology & Engineering
Languages : en
Pages : 220

Book Description
artensite forms under rapid cooling of austenitic grains accompanied by a change of the crystal lattice. Large deformations are induced which lead to plastic dislocations. In this work a transformation model based on the sharp interface theory, set in a finite strain context is developed. Crystal plasticity effects, the kinetic of the singular surface as well as a simple model of the inheritance from austenite dislocations into martensite are accounted for.
