The cases demonstrating that computer modeling can help preclude failure of heat treated parts by taking into consideration the operating requirements of the part and the specific heat treatment are presented. Certain design features make a part prone to overheat upon induction heating such as parts containing longitudinal and/or transverse holes, keyways, grooves, shoulders, flanges, diameter changes, undercuts, hollow areas, splines, and sharp corners. Mathematical modeling helps determine optimal process parameters and inductor design and evaluate the robustness of a particular hardening process by estimating the impact of real-life process deviations at certain temperatures. Selection of appropriate process parameters often reduces hot spots around the hole and eliminates cracking. Inductor profiling also dramatically reduces hot spots. Computer modeling provides vital assistance in determining optimal inductor profiling. Predicting the formation of stresses during and after induction hardening requires expert modeling and simulation. Source

This reference provides practitioners, students, engineers, and scientists with the knowledge to better understand the various interrelated physical phenomena of induction heating and heat treating. Much of the content in the 62 articles in this handbook has not been published before. To provide a snapshot of the wealth of information contained in Vol 4C, a series of brief articles highlighting some of material in different chapters are now being published in subsequent issues of HTPro. The review articles are authored by Valery Rudnev (Professor Induction), who together with George Totten served as co-editors of the handbook. Source

Recently published ASM Handbook, Volume 4C is specifically devoted to needs of Induction Heating and Heat Treating community (Fig. 1). It is a long-awaited expansion of the ASM Handbook series. Heating by electromagnetic induction is a topic of major technological significance that continues to grow at accelerated rate in a variety of induction thermal applications such as hardening, tempering, stress relieving, brazing, soldering, shrink fitting, melting, normalizing, annealing, coating, as well as re-heating ferrous and non-ferrous metallic materials prior to warm and hot working. As such, ASM Handbook Volume 4C: Induction Heating and Heat Treating reflects an ambitious undertaking to compile an all-new, comprehensive resource on induction thermal processes in the 21st Century [1]. World-recognized experts from leading universities, national research laboratories and industrial corporations from 10 countries contributed materials published in this Volume making it a truly international effort in describing leading-edge induction technologies. © 2015 ASM International®.

This paper will address practical aspects of developing induction heat treatment processes - induction hardening processes in particular. Examples will be presented to illustrate methods of improving inductor and process designs utilizing computer simulation. A number of everyday challenges encountered by heat treatment practitioners will be addressed, specifically challenges related to metallurgical and mechanical quality. The value of utilizing computer simulation will be demonstrated in these real-world solutions through the revelation of subtle facets of induction heat treatment that cannot otherwise be physically observed or measured. © 2015 ASM International®.

In the last decade, when discussing subjects related to a computer modeling of induction heating and heat treating, the word "usefulness" has been replaced by the word "necessity." Modern computer simulation is capable of effectively simulating electromagnetic and thermal phenomena for many processes, including those that involve electromagnetic induction. This article discusses the state-of-the-art computer simulation of induction heating and heat treating providing answers to following questions: Why finite element analysis is not always the best tool for computer modeling of some induction heating applications? What are the limitations of generalized all-purpose commercial programs? What are the crucial tips that executives must know regarding computer modeling of induction heating? Several case studies will be reviewed in this article as well. © 2013 ASM International. Source
