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.

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discussing subjects related to a computer modeling of induction heating and heat treating, the word "usefulness" has been replaced by the word "necessity."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.


A single shot inductor is provided to induction heat treat closely spaced multiple eccentric cylindrical components arranged along the longitudinal axis of a workpiece. The single shot inductor has multiple planar arcuate single turn coil sections separated from each other by an axial coil section so that each of the multiple planar arcuate single turn coil sections sequentially heat treats the closely spaced multiple eccentric cylindrical components inserted within the single shot inductor.

A single-shot inductor is provided to induction heat treat a complex workpiece that has an at least partially cylindrical component with its central axis coincident with the central axis of a circular component and connected at one end to the circular component with a diameter larger than the diameter of the at least partially cylindrical component. The single-shot inductor has a single crossover inductor section connected to the first ends of two longitudinal leg inductor sections with the second ends of the two longitudinal leg inductor sections connected to a collar inductor section that surrounds the entire circumference of the at least partially cylindrical component when the complex workpiece is loaded in the single-shot one-turn inductor for an induction heating application. Alternatively the single-shot inductor may have two collar inductor sections interconnected between two longitudinal leg inductor sections where one of the leg sections can accept a supply of alternating current.

ASM International, Materials Park, Ohio, announces that organizers for Heat Treat Mexico are currently seeking abstract submissions on heat treating topics for the upcoming new event in Queretaro, Mexico, to be held later this year in September. It is the first show by the ASM Heat Treating Society specifically focused  on thermal processing technology in Mexico, and organizers expect to reach a broad audience of heat treating professionals. As the January 22nd deadline to submit approaches, organizers encourage the heat treating community to submit their research and take advantage of the opportunity to present at Heat Treat Mexico. The organization of this technical program is slightly different from other heat treating shows from HTS, as it will focus on three overarching topics, one on each of the three days: Process, Meaning to metallurgy, and Application. The technical program is organized to emphasize how the materials respond to thermal treatment.  Attendees will gain a higher level of understanding for several methods of heat treating, such as vacuum carburizing,  nitriding, and induction hardening. This unique opportunity highlights the fundamentals of the process on day one.  Changes to the metallurgical structure that result from the treatment will be covered on day two, and control methodology and maintenance protocols important to the specific technology will be highlighted on day three. Robert J. Madeira, Vice President of Heat Treating for Inductoheat Inc., thinks that attendees will find great value in this show. "ASM International and its legion of industry professional recognize the opportunity to bring its expertise in education to Mexico.  The "Basics of Metallurgy" course and the three day Heat Treating Symposium will be taught simultaneously in Spanish and English. This content-rich forum is designed to deliver expert knowledge about how modern thermal treatments transform metals.  It offers the foundation for understanding that leads to good decisions on the factory floor." To submit an abstract for Heat Treat Mexico, visit the Heat Treat Mexico website and select your preferred topic, along with the specific facet.  For example, "Induction Heat Treating; What is the Process?" Presenting authors will be notified in February 2016 as to the status of their abstract. As the world's largest association of metals-centric materials engineers and scientists, ASM International is dedicated to informing, educating, and connecting the materials community. A member and volunteer based organization, ASM serves as a central resource that gathers the latest applied information from the field and disseminates it back to industry, academia, and government through published content, classes, conferences, expositions, and local chapter engagement.
