Abstract
Tempering of induction-hardened steel is a form of subcritical heat treatment, primarily carried out to increase ductility, toughness, and dimensional stability, to relieve residual stresses, and to obtain specific values of mechanical properties. This article describes tempering with emphasis on different time-temperature exposure requirements for furnace and induction tempering. It discusses two parametric methods for correlating equivalent time-temperature condition: Hollomon-Jaffe tempering correlation and Grange-Baughman tempering correlation. The article describes different methods of induction tempering, namely, single-shot, progressive or continuous, scanning, and static heating methods. The effects of induction heating variables and hardenability on tempering response are examined. The article also provides examples of how tempering affects the mechanical properties of induction-hardened steels.

Abstract
Induction heat treating is used in the off-road machinery industry for hardening steel and cast iron components used in a wide range of applications. This article focuses on the usage of induction hardening components in the industry, and discusses the basic requirements of steel and cast iron to undergo induction hardening. It provides a comparison on single-shot and scan hardening methods to select the suitable one for induction heat treating of gears and sprockets. The article describes the effect of microstructure, residual stress, and workpiece position on induction hardening. It concludes with a discussion on the important factors to be considered during the installation of off-road machinery components.

Abstract
Induction heat treatment is a common method for hardening and tempering of crankshafts, which are necessary components in almost every internal combustion engine for cars, trucks, and machinery, as well as pumps, compressors, and other devices. Similar to crankshafts, camshafts also belong to the same group of the critical engine/powertrain components. This article focuses on induction technologies used for surface hardening and tempering of automotive crankshafts, and provides general information on U-shaped inductors with crankshaft rotation and clamshell or split inductors without crankshaft rotation and their pros and cons. It also describes the effect of post-heat-treatment processes in crankshafts. The article concludes with a discussion on induction hardening of camshafts that focuses on those used in automobiles and truck engines.

Abstract
Induction hardening involves multiple processing steps of heating and quenching which presents opportunity for errors and defects. This article discusses the common problems associated with induction hardening of shafts as well as the methods to diagnose, inspect, and prevent them. In addition to the major defects such as laps and seams that remain after induction hardening, microstructural transformation, decarburization, residual stress, and grain size, as well as variations in carbon content, composition, or microstructure can also affect the hardened part.

Abstract
Tempering of steel is a process in which hardened or normalized steel is heated to a temperature below the lower critical temperature and cooled at a suitable rate, primarily to increase ductility, toughness, and grain size of the matrix. This article provides an overview of the variables that affect the microstructure and mechanical properties of tempered steel, namely, the tempering temperature, tempering time, carbon content, alloy content, and residual elements. Tempering after hardening is performed to relieve quenching stresses and ensure dimensional stability of steel. The article discusses the embrittlement problems associated with tempering. Four types of equipment are used for tempering, namely, convection furnaces, salt bath furnaces, oil bath equipment and molten metal baths. Special procedures for tempering are briefly reviewed.

Abstract
This article commences with a description of the principles of induction heating followed by a discussion on the high temperature electrical, magnetic, and thermal properties of steel, which influence the performance of induction heaters. The importance of eddy current distribution in a workpiece is explained, with emphasis on the skin effect. The article discusses typical procedures for induction hardening of steel, namely, austenitizing and quenching to form martensite either on the surface (case hardening) or through the entire section (through hardening). It briefly describes induction heating parameters for surface hardening, through hardening, tempering, and some general heating operations in metalworking.
