A US patent was just issued in February of this year for a new family of super high speed steel alloys that I invented. You can read about them here:

These grades are so new that they don't even have an official name yet. That's one of the reasons why I am posting...
For those of us based in the United States, have any of you performed consulting work for any countries in the EU? If you have, what were the tax implications? If, for example, you traveled to the UK to perform this work, do you owe any taxes to Great Britain at the end of the year? And how does...
We have a die set-up for fixture quenching parts during heat treatment. The parts are removed from the austenitizing furnace at 1560F, and placed onto a room temperature steel table ring and then retracted into the machine where they are oil quenched. The elapsed time from furnace to quench...
I have been tasked with identifying the requirements we must satisfy in order to obtain NADCAP accreditation in our heat treating operations. I contacted the Performance Review Institute (PRI) which is the only auditing company I know of that is approved by the aerospace industry to perform...
These "small" volcanic eruptions are being viewed by some scientists as potentially having a greater influence on earth's climate than was previously believed:

This would be an awesome high school class project for those of you with children that age.

We have different sets of steel tongs that are used for manually transferring hot parts out of our austenitizing furnace and into our fixture quenching machines. At the point where the tongs contact the hot parts, there is some heat transfer. For the thicker parts this doesn't really cause any...
I'm in the process of renovating a metallurgical laboratory, and need to purchase a wall mounted chart that I can place near the microscope for rating non-metallic inclusions per ASTM E45. I have been unable to find anyplace that sells these charts. Does anyone know where I can source one...

What ASTM specification covers allowable decarburization limits on 8620H forgings for use in gearing applications? I don't have access to the necessary reference materials to look it up, and was hoping that someone here would be able to identify it. Thanks.

This is a classic text that may be of interest to the metallurgical experts...
A topic of discussion that was recently broached by myself and another professional engineer is the subject of liability. He recently decided to go out on his own and start a manufacturing company to produce specialized products for use on satellites. He just started an LLC, and I asked him what...
We have a carburizing line in our industrial heat treating operation, and are processing typical carburizing grades such as AISI 8620 and 9310. As a part of this process, we use a copper plating bath to selectively apply a thin copper layer as a stop off to prevent certain areas on these parts...
I have been asked to provide AISI equivalents to these Japanese grades, but was unable to find them listed in either Woldman's or in the Stahlschlussel reference books that I have on hand. An internet search also came up empty. Can anyone provide the equivalent grade designations (if there are...
This link provides access to free copies of a number of metallurgical texts ranging from Georgius Agricola's De Re Metallica (which, oddly enough, was translated into english by none other that Herbert Hoover) to DuPont's 2009 publication of Welding Metallurgy and Weldability of Nickel-Base...

I have an opportunity to perform consulting work for an out-of-state corporation. My current full time employer has given me the green light to proceed with this project (and I have it in writing) provided that I do not utilize any company owned resources, to which I have agreed. In order to...
Do the practicing professional engineers out there who work as consultants in industry typically enter into individual contracts with your clients? Or do you just send them an invoice after completing the work? Most of the PE consultants that I know simply get a call, show up, and do the work...
For those of you who are interested, the book "Metallurgy of Steel for Bladesmiths & Others
who Heat Treat and Forge Steel" by John Verhoeven is available online. It's a well written introductory text on metallurgy, and may be of use to those of you who work with steel alloys. Here is the link...
