multiple hardening cycles?

[Troop]

Whether you do it earlier and call it normalizing, or you do it last and call it multiple quenching, that cycling through the transformations is what refines the grain.

But, Rick, with air-hardening steels, it's different. You really can't "normalize"' air-hardening steels.

True... Air hardening steels are the Devil.... it just ain't natural for steel not to rust, man.....:grumpy:

In otherwords, I can only speak for carbon steel, as that is what I use. Thanks for catching me on that.:thumbup:

The grain refinements effects are limited by multiple cycling treatment , especially within 100C above the critical temperature.So I think cycling more than twice is not necessary.Just some advantage of cycling is that the alloy elements is to be homogenized.

What's the best book on metallurgy so I can figure out exactly what you guys are talking about? I've just recently began forging my own blades and want the most knowledge possible. I know this is off topic and I'm sorry for hijacking your
Thread but there is a good discussion going here.

These books are good

what about A2??
(I haven't had any rust yet, but have presumed it would...)

Stop ruining my jokes with intellect.

actually I'm ruining them with ignorance, but the result is the same.
