Hello All. I am getting my @$$ kicked by what seems to be a simple concept, and I hope someone can offer me a little help.
With some of the nickel based super-alloys such as what are used in turbine blades, why do the alloys get stronger as they get hotter? It seems counter-intuitive to me. Red hot metals are not typically "stronger" than those at room temperature. However, these blades withstand temperatures well beyond what it takes to melt most other metals and turbine blades remain strong. Is it because of the coatings? Is it because the additional heat creates a coalescence of the material and further heat treats it?
I hope I posted this in the correct forum. I only recently signed up with PF but I have frequented the site for some time now. I thank anyone and everyone for all the help provided.
