Thread: Interupted quench??

As I mentioned, Kevin Cashen can explain this interrupted quench stuff better than I, so I'll let him do it. The video clips I am posting are from Kevin's Heat Treating Demo/Lecture at the Ashokan Bladesmithing seminal in 2006. For those who don't know, Kevin is a Master Smith in the American Bladesmiths' Society, and he knows his beans about heat treating. (By the way, the geek tape on the glasses was one of Kevin's jokes.)

The steel Kevin is used in the demo is 1084. I believe he was quenching in Park Metallurgical's #50 quenching oil. I actually weaseled the knife blade out of Kevin at the end of this demo, and I still have it.

For anyone who needs the proper temps for heat treating 1084, I'll post the pages on it from the Heat Treater's Guide. They don't show a TTT chart for 1084, so I'll post the one for 1080.
