Processing variables are confounded when different alloys enter a heat treatment facility. Cooling temperatures and time periods adjust accordingly to metallurgical variances. Likewise, a worked hardened metal part is subjected...
Material strength isn’t a straightforward property, not when we’re talking about structurally-capable alloys. Yes, a hardened workpiece is stiff, but it could also be brittle. In reality, strength is an...
Robust metals are often judged on hardness. It’s a term that’s closely related to the stiffness of an alloy, which is all well and good, but what about ductility? What...
If heat treatment technology has ever been perceived as an afterthought, well, nothing could be further from the truth. This is an essential process regimen, a series of techniques that...
This fully contained heat treatment procedure is usually tendered by Alpha Detroit when a workpiece requires a mechanically enhanced, metallurgically consistent finish. Therefore, to answer the initial question, it is...
Induction hardening technology doesn’t use physical contact. Instead, a series of magnetic fields are projected from a large coil. Workpieces enter the coil, experience this induction effect, and respond by...
The flame hardening process functions as an exceptional surface hardening solution. Its gas-generated flame hardens selected areas on command, then switches tact to heat treat large surface areas, no matter...
Induction hardening technology employs a refined control setup, with magnetically induced energy patterns acting as a contact-free heat treatment mechanism. A hardening profile is established by the induction station’s electrically...
Workpiece hardening is a central part of any heat treatment facilities’ work output, so it’s only logical that several alternative techniques should develop in response to this need for mechanical...
A black oxide finish imbues a worked ferrous component with an attractive ebony coating. The process transforms a thin layer of surface metal into iron oxide, so no deposits are...
Large-scale engineering projects use machined metal components to support structural loads. They accomplish this task by accessing the strength of a selected alloy. Unfortunately, strength isn’t the only attribute contained...
Hot die materials are burdened with a formidable task, which is an elaborate way of saying high temperatures and higher pressures are at work. The forging process applies compressive force...
As we discuss carbonitriding, expect to be carried through a heat treatment process that relies heavily on the control of local atmospheric variables. In particular, as the label implies, carbon...
Gears and wheel sprockets are low profile components, but that understated physical form belies an innate knack for handling near unendurable loads. Geometrically detailed, these essential mechanical parts are machined...
High tolerances rule hot and cold precision straightening work. The factory floor is filled with high-tonnage presses and industrial grinding stations, the larger-than-life tools that enable expert material engineers to...
When troubleshooting heat treatment imperfections in vacuum ovens, the undesirable results that stymy production engineers don't always fall into convenient pigeonholes. Fortunately, the discolouration of metal parts that have undergone...
Flame hardening operations extend the operating life of alloy-rich components by adding rigid strength to the microcrystalline backbone of the heat-treated part.
Heat treatment techniques use a two-step processing methodology. Logically, it begins with the workpiece entering a fiery environment, perhaps a gas-fired furnace. Here, the metal component is subjected to enough...
Work hardened metals are difficult to form. The machining and shaping work has impacted the material in such a way as to cause the metal’s grain to compact and shrink.
If we've placed a great deal of emphasis on materials, there's a good reason for this seemingly off-kilter approach. Materials must be heat treated if the mechanical and physical properties...
The principal objective of this discussion is to determine the causes of distortion and residual stresses in heat treatment.
Fine manufacturing processes create sturdy cast iron items and robust steel-reinforced components that resonate with structural soundness, but such mechanical solidity doesn't just happen, not without an incorporated processing stage...
In the foundry, blazing hot furnaces melt metal and produce castings, parts that are imbued with crude properties. It is then down to special alloy-refining facilities to alter those material...
In documenting the essential characteristics of the black oxide coating process, we've illustrated the engineering science and the main advantages of the procedure. More than a smart finishing process, a...
