How Does Grain Refinement Improve Steel Properties?

Yes, Larrin. Given the number of "I think" or "maybe" or "It's probably because" I see on other forums, I appreciate scientific, accurate answers. Although, since my Material Science classes (do they even call them that anymore?) were about 50 years ago, I have to admit I only understand about 50% of what you are saying. But hey, every little bit helps. Now, if you could just explain what makes a knife sell I would go out to the shop a happy man.

I’m smiling and clapping too and pretending to get it. Maybe someday.
Thanks for taking your time to educate though, it’s good to know this forum has accurate information.

That's certainly worrying when it comes to the quality of my writing, as I would like it to be understandable by as wide an audience as possible.

Well, if I can get it, most folks will. Not to say that a few months from now, I won't completely forget it all. Ancestry.com says I have 23.7% Goldfish DNA so after a lap around the tank, it's all new territory.

Don’t worry and don’t wait on me. I’ll catch up. Keep doing what you’re doing!

That's another reason I'm writing these articles. I keep re-reading the same things over and over instead of keeping a record of anything. Now I will have convenient access to my past self's thoughts, complete with references.

Is the grain boundary sliding you mention possible at room temperature? I've only seem it mentioned in elevated temperature applications.

Typically that is true unless there is a very high area of grain boundaries from the ultra fine size. I do believe there is some debate about the mechanism of the effect, however. Some don’t think that grain boundary sliding is the mechanism.
