How to perform a high temper

[Willie71]

We are talking about tempering here but I think you should experiment with lower aus temps. For knives you will gain some toughness and lower retained austenite with lower austenitizing.

Try 2100-2150f

I think I used 2100f for the charpy samples. I did cryo plus low temper, and no cryo/high temper @1000f. Stormy is experimenting a lot with M2 right now, so maybe he can do a pair of samples done at 2200f for comparison. If he can’t, I can add that to my next batch of samples.

X-ray diffraction was discovered in 1912, and major studies on steel with XRD started in the early 1920's. The fundamental capabilities of the equipment haven't changed substantially in many decades.

Have PhD from 1996 in X-ray crystallography of proteins (even more complex than steel), can confirm.

Sorry I've missed this thread . remember that there are two factors here , reducing RA and stabilizing any remaining RA. the two sometimes fight each other ! Precision die work is one thing that will bring up the challenge .
