As the name implies MARquench or MARtemper gives you martensite. Austemper gives you bainite. Both of these are heat treating processes.Ausforging is the forging of the steel after the temperature has dropped below the critical temperature but before the austenite has begun to transform. When the piece is in the 'austenite bay ' there is a limited time when it can be forged or worked but significant strength increases can occur.It's more applicable with higher hardenability steels since the austenite bay is larger and you have more time.

I thought of that too but I didn't want to bring up the dreaded 'e---- p----' term !!

Hmm... let's see if I understand this then. So marquench/tempering and austempering are both approximately the same process, quenching into a hotter then usual medium and leaving it in there for X amount of time, the main difference between the two being how hot the quench medium is(below vs above Ms)? Does that seem like I got it or am I still way off base?

Except that the X amount of time is short for marquenching and long for austempering.

Got it, thanks.
