Metallurgical Aspects of Induction Heating, Microstructures, Residual Stress [.pdf format]

Metallurgical insights for induction heat treaters. Part 1: Induction hardening temperatures

Authors: Valery Rudnev
Publication: Heat Treating Process, Professor Induction Series
Date: 5/1/2007

This article is one of series of articles devoted to metallurgical aspects of induction hardening. Hardening of steels and cast irons represents the most popular application of induction heat treatment. The three most common forms of induction hardening are surface hardening, through hardening, and selective hardening. Intricacies of selecting induction hardening temperatures and phase transformation diagrams are discussed in this article.

"Fine Print" of Metallurgy of Induction Hardening, Part 2

Fine prints became one of the characteristics of our life. It turned into a normal practice to be aware about fine prints of disclosure in every aspect of life whenever we are buying goods or listening to advertisements, taking medicine or purchasing service. In many cases "fine prints" consist of more important information than the large print. This article discusses in this two-part article the "fine prints" of certain metallurgical phenomena and principles of heat treatment that frequently are incorrectly assumed or improperly used in induction hardening.

Steel selection for parts to be induction heating lays a critical role in determining if the required properties can be achieved in the hardening process.

Residual Stresses in Induction Hardening: Simply Complex

Authors: Valery Rudnev

Heat treaters are often faced with the necessity of making a reasonable compromise between maintaining the required hardness and obtaining a tough, ductile microstructure that has the desired distribution of residual stresses. Stresses can be classified in several different ways. In general, stresses that appear during induction heat treating can be divided into three groups: initial, transitional, and residual stresses.

Troubleshooting Cracking in Induction Hardening

The development stage was completed, the induction hardening machine was built, run-out was successful, and the machine was shipped to the customer's plant. Either right away or after a number of successful production runs, hardened parts started to crack. Unfortunately, this situation is not uncommon. This article presents a troubleshooting strategy to correct cracking problems in induction hardening.
