Preface The first edition of the Steel Heat Treatment Handbook was initially released in 1997. The objective of that book was to provide the reader with well-referenced information on the subjects covered with sufficient depth and breadth to serve as either an advanced under- graduateorgraduateleveltextonheattreatment orasacontinuinghandbookreference for thedesignerorpracticingengineer.However,sincetheinitialreleaseofthefirsteditionofthe Steel Heat Treatment Handbook, there have been various advancements in the field that necessitatedthepreparationofanupdatedtextonthesubject.However,withtheadditionof new chapters and expanded coverage, it was necessary to prepare this updated text in two books. Steel Heat Treatment: Metallurgy and Technologies focuses on steel heat treatment metallurgy while this text addresses heat treatment equipment and processes. Steel Heat Treatment: Equipment and Process Design contains updated revisions of the earlier Steel HeatTreatmentHandbookwhile otherchaptersarenewtothis book.Thechaptersincluded in this bookare: SECTION I—EQUIPMENT Chapter1. Heat TreatmentEquipment Chapter2. Designof Steel-Intensive Quench Processes Chapter3. Vacuum Heat Processing Chapter 4. Induction Heat Treatment: Basic Principles, Computation, Coil Construction, and Design Considerations Chapter 5. Induction Heat Treatment: Modern Power Supplies, Load Matching, Process Control, and Monitoring Chapter6. Laser Surface Hardening SECTION II—TESTING METHODS Chapter7. Metallurgical Property Testing Chapter8. Mechanical Property TestingMethods This book is intended to be used in conjunction with Steel Heat Treatment: Metallurgy and Technologies. Together, both books provide a thorough and rigorous coverage of steel heat treatment that will provide the reader withan excellentinformationresource. GeorgeE.
