That is incorrect. "Solution" heat treating refers to dissolving all the alloying elements into a solid solution. The heating can be by any number of methods. For small parts an air oven is fine.

I assume we are really talking about the 2117 alloy rivets we get in the kit. This alloy is solution heat treated at 935F followed by a rapid quench and age hardens. I would not mess with the other rivet types and definitely would not anneal any of them (lower temperature and slow cooling) as that would put them in the "0" temper!

That might be an "apples vs. oranges" point, but I agree yours is a more accurate technical description.

There was a "How it's Made" episode that described submersing formed ribs in a salt bath as solution heat treating.

I associate "Solution" as you used it for what happens at the molecular level, not the "process" level. In the sheetmetal formus I've presented at Sun'nFun and OSH, no one raised that distinction.

Guess I was a little intellectually lazy!

Holy cow! I never heard of this! You learn something new on VAF every day it seems like.

Thanks guys!
