Inducing Heat Treatment for Case Hardening
Induction hardening has become an increasingly popular heat-treatment method for steel due to its extremely fast processing speeds. Compared to other case hardening methods, the processing times are on the scale of seconds or minutes compared to hours in a carburization furnace. Typically a

Metal Plasticity in Manufacturing
Understanding the plastic behavior of steel plays a crucial role in manufacturing. From raw billet to parts in service, some form of plastic deformation can be found in every step of the manufacturing process, heat treatment not excluded. In fact, I used to joke in Materials and Manufacturing

Heat Treatment Process Modeling Development for Age-Hardenable Alloys
Age-hardenable alloys, such as some aluminum alloys, maraging steel, and nickel-based alloys, get their strength not from quenching but from the precipitation that occurs during the aging or tempering process. While the types of precipitates are different for each alloy, the mechanism is similar. Du

Learning From Failure in Bending Stress
A couple of years ago, as I was finishing my graduate studies, I was lucky enough to participate in the Strong Bar competition put on by the ASM Heat Treat Society at the Heat Treat Show 2021. This competition challenges university students to design and execute a heat treatment of their choice on a

Using Welding Simulation Tools to Model WAAM
A common practice when developing a WAAM process is to build small “walls” by depositing material layer by layer on a build plate and then machining mechanical and microstructural samples to quantify the properties provided by the process. For this study, a simple finite-element model was constructe

Characterizing Equipment Using Simple Modeling Tools
For this article, time-temperature data from a salt bath heating and high-speed water quench process will be examined. A utility tool originally developed internally at DANTE Solutions and now available to the public, called HTCFit, is used to determine the Heat Transfer Coefficient (HTC) that the

Carburization
Strong Bar Competition
The metallography was performed in the lab of Cleveland State University. First, a bar was chosen to be cut cross-sectionally with the diamond disc cutter. After the section was cut, the sample was polished with 4μm diamond paste and a polishing pad.

Wired For Cooling – Thermocouple Fin Effect
Thermocouples are one of the most practical and widely used tools for gathering time/temperature data in thermal processing environments. Ranging from laboratory-scale experiments to full industrial heat-treatment operations, these sensors provide direct insight into how materials respond to heating

Scanning Induction Hardening of Steel Coupler
Casing components experienced cracking problems during an induction hardening process. The casing has an OD of 32 inches and is 20 inches tall. The CAD model of the component, as well as the region of high cracking potential, is shown in the figure. DANTE Heat Treatment Simulation software was used
