One of my favorite television programs (and I suspect many other heat treaters) shows and demonstrates the early forging techniques that were used to make knives, swords, axes, etc.

I have often addressed the effects of induced mechanical stresses in the metal and the ways that those stresses affect the dimensional movement when the metal is subjected to thermal conditions (hot or cold). The question is often asked: How long does it take to remove the induced mechanical stresses caused by physical mechanical conditions being applied to the metal (e.g., machining stresses)?

Most heat treaters have been told by in-house customers, as well as external customers, that we need to have the component “heat treated without distortion.” That is essentially an impossibility.

Do you need motivated? Here's some quotes David Pye compiled that just might help.

This is the second part of David Pye's series on surface treatments.

This blog will discuss a brief comparison between low- to high-temperature-deposition methods of surface-modification treatments in relation to thermal-diffusion treatments.

David Pye's series on the heat treatment of exotic metals continues.

Since those early days of the birth of what became known as the “jet age,” titanium alloys have found a strong demand by manufacturers.

In terms of current industrial requirements, the most interesting subject to the writer is the treating for bio-implant items and “repairs” to components that are inserted into the human body.
