How Does Hardening and Tempering Improve the Strength of Materials?

28 April 2017

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 amalgamated property, something that combines hardness and material tempering. In using metal solidification technology as our starting point, we’ll explain […]

Stress Relieving and Hydrogen De-embrittlement

13 April 2017

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 of plastic deformation and tensile strength? A material that’s solely engineered to be stiff is likely to hold its shape, […]

Heat Treatment: A Critical Process that should not be an Afterthought in Large Engineering Projects

24 March 2017

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 equips metal parts with tailored material properties. Hardness is usually regarded as the primary reason for altering these already robust […]

Is it Possible to Oil Quench Materials from a Vacuum Furnace?

23 March 2017

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 possible to oil quench materials from a vacuum furnace, but this technique should only be called upon when superior mechanical […]

Induction Hardening: Cheaper and Faster for Large Volume Repetition Hardening of Pins, Axles and Shafts Compared to Flame and Case Hardening

23 February 2017

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 generating surface heat. That workflow suggests a production line of some kind. If so, is its ever-cycling configuration preferred over, […]
