Induction hardening steel to austenitic temperatures can result in temper back, or annealing of adjacent areas of the material that have been hardened previously. This is particularly important in the induction hardening of crankshafts, camshafts, gears and critical components. This publication discusses above mentioned effect along with some other important features of induction hardening and [...]
In some applications heat treating by induction faces certain challenges. Typical examples would be applications where the workpiece contains longitudinal and / or transverse holes, keyways, grooves, various orientations of hollow areas, sharp corners and other discontinuities. Existence of these features can result in undesirable appearance of hot and cold [...]
The selection of forging temperatures for steels is based on carbon content, alloy composition and forging specifics, including the temperature range for optimum plasticity and the amount of reduction. Based on these considerations, optimum forging temperatures that result in the material’s lowest flow stress (lowest forging pressure) are selected.

If the induction coil contains numerous brazed joints and, in particular, if there are 90° joints, then water flow in cooling coil turns could be impeded. This problem is more likely to occur if small diameter tubing is used for coil fabrication. As a result, booster pumps may be needed to provide sufficient pressure for [...]

Induction heating of the internal surfaces of a workpiece for applications such as hardening, tempering, annealing, shrink fitting, and brazing has several unique features related to the physics of the process and the selection of process parameters, compared with heating of external surfaces. There are four main [...]
Radyne offers many fully integrated induction heating systems for the production of munitions which are utilized by both the military and commercial munitions industries. Radyne bonding and annealing systems are used to make bullets for our Law Enforcement, Military, and for the Hunting and Shooting Enthusiast. Radyne has a well established history of designing [...]
Gears are induction hardened by either encircling the part with a coil (so-called spin hardening) or, for larger gears, hardening them “tooth-by-tooth” or “gap-by-gap.” Article concentrates on analyzing main coil failure modes of “gap-by-gap” inductors for hardening large and medium size gears. Several case studies are discussed including degradation of [...]
Numerical computer modeling is one of the major factors in successful design of induction heating systems. In the fast-pace global economy, the ability of induction heating manufacturers to minimize the development time and shorten the “learning curve” through efficient computer modeling is critical for a company’s success.

Fiber is manufactured by heating a susceptor to an elevated temperature and sustaining the temperature of a large diameter bar/rod of Quartz or other similar material used to make the fibers. The heat causes a section to slowly pull down to manufacture the proper diameter fiber required. This larger starter end is connected to a [...]
