This is the 100th column for "The Heat Treat Doctor"! So, how do we celebrate? By asking ourselves the most fundamental of questions: What is heat treating, and why do we do it? Let's learn more.Daniel H. HerringIndustrial Heating...
In simple terms, heat treatment is the process of heating the metal, holding it at that temperature, and then cooling it back. During the process, the metal part will undergo changes in its mechanical properties. This is because the high temperature alters the microstructure of the metal. And...
Laser Heat Treatment in Locomotive ManufacturingLaser heat treatment is being increasingly adopted in the large locomotive manufacturing industry to enhance the durability of locomotives. It involves treating critical components like crankshafts, cylinder liners, and main springs of locomotive diesel engines...

For years, military specification Mil-H-6875, often referred to as the bible of heat treating, never distinguished between "raw material" and "parts." Although raw material was viewed as steel that is processed in steel mills, forging and casting shops, and parts were the materials typically ...
When it comes to using ice and heat for treating knee injuries, it's important to keep in mind thatboth ice AND heat are very effective ways to relieve pain and heal. Most people will think one is better over the other from their own experience or what a doctor / physical therapist has...
– it may be a precipitation hardening treatment, or a softening treatment, depending on the material. However, this process can be costly and time-consuming and may not offer a complete solution. Heat treating is also limited by the comparative size of the part and the torch or furnace ...
i.Induced force. An example is shown in the figure below, where a permanent magnet is dropped into a copper tube. The induced force according to the Faraday’s law tries to stop the magnet’s motion inside the tube. ii.Induced heat.When an electrically conductive material is exposed to an...
Induction heating is used both domestic and commercial cooking, in several applications such as heat treating, soldering, preheating for welding, melting, shrink fitting in industry, sealing, brazing, curing, and in research and development. How Does Induction Heating Work? Induction produces an elect...
Temperature profiling is the term used to describe the process of recording and interpreting the temperatures of products and/or air through a conveyorized heat-treating process. Temperature data is measured continuously using thermocouples connected directly to the product(s) at dif...
