Speaking of comparisons, three of the seven reader favorites compare induction with alternative processes. In fact, the most-read induction article was the third-most-popular article overall in 2017, and it compares induction and case hardening.


Comparing Induction Hardening, Case Hardening

Reducing fleet consumption in the automotive industry or service-free lifetime operation of components in offshore oil rigs all depends on the quality of the components used. The heat treatment – here the surface hardening – plays an important role for keeping geometrical dimensions as small as possible and boosting the component’s resistance to ever-increasing loads at the same time.

This article, originally run in August 2015, discusses the advantages of induction heating and provides some specific examples to compare costs. Induction is well-suited to being incorporated into production lines due to the custom hardening configurations available. You can find this article at www.industrialheating.com/indvcase.


Comparative Analysis of Induction and Furnace Tempering

Another comparison article was originally run in December 2016. The Center for Heat Treating Excellence (CHTE) at Worcester Polytechnic Institute (WPI) in Massachusetts performed a one-of-a-kind research project aimed at better understanding the mechanical properties and microstructural features of steels that have been gas tempered and induction tempered. Ultimately, the findings from this induction and furnace tempering research project will help industry, especially heat treaters in the automotive industry, reduce cycle time and process costs while maintaining or improving product performance of toughness and strength.

For this study, AISI 4140 was used for its high hardenability and because it is widely used in engineering applications. Check out the findings, which compare microstructure and mechanical properties (hardness, tensile and impact toughness). You can find it at www.industrialheating.com/comparetemper


Gear Materials and their Heat Treatment

The next-most popular “induction” article is not really an induction article. It is actually a third comparison article of heat treatments for gears. Gears play an essential role in the performance of many products that we rely on in our everyday lives. When we think about gears we generally separate them into two categories –motion-carrying and power-transmission. Motion-carrying gears are generally nonferrous or plastics, while load-bearing power-transmission gears are usually manufactured from ferrous alloys and are intended for heavy-duty service applications.

This article discusses gear materials and the properties necessary for demanding gear applications. Atmosphere, vacuum and induction processes are compared. For more, go to www.industrialheating.com/gearht.


Flash® Processing for High-Strength, Cold-Stampable Automotive Steel

Flash® processing of common steel is a promising manufacturing technology that can be used to produce high-strength, cold-stampable automotive steel for safer, lighter and more fuel-efficient vehicles. Flash processing is an extremely rapid heat treatment with a total process time of less than 10 seconds. Room-temperature or preheated steel is fed into an induction heating unit that heats the material at a rate of approximately 400°C/s to temperatures above 1000°C (1832°F).

This interesting article was contributed by the U.S. Department of Energy in May 2017. You can find it at www.industrialheating.com/flash.


10 Considerations When Selecting an Induction Heating System

If you are in the process of considering induction for your facility, this article might be just what you need to read. Originally run in August 2016, this article steps through what to consider in your decision, which includes things like the materials to be processed as well as your part/coil shape and your plant logistics.

You will learn a general rule that the higher the frequency, the shallower the heating of the part. This may be more intuitive if you also consider that higher frequency also means lower power. Originally in the August 2016 print issue, this article can be read online at www.industrialheating.com/induction10.


Using Induction  Brazing in Manufacturing Operations

This article was actually run in two parts in 2016, and both were very popular with readers. Induction is an excellent way to quickly heat up a localized area of a large assembly in order to permanently join them together. The induction-brazing process is examined to see what it is and how it can be effectively used by brazing shops to meet some of their production needs.

Induction brazing is a wonderful tool that many shops may wish to use for certain parts that need to be brazed quickly, are too large to fit inside a brazing furnace or perhaps have areas that cannot tolerate high heat since damage might result to those areas if heated to brazing temperature. It is safe, fast and very reliable when proper procedures are followed.

Design and Development of PPAP-Ready Wheel-Bearing Inductors

Did you know induction hardening requires a six-degree design equation to predict how a wheel bearing will respond in an induction field? Although great strides are being made to simulate induction patterns, most of today’s inductor design and validation is still done through experience and experimentation. The objective of this article is to show how a wheel-bearing inductor is designed, fabricated and validated to be ready for Production Parts Approval Process (PPAP) and integration into robust manufacturing.
