The question is clear, and the answer is obvious. Time of exposure - easy peasy. Now, if only all exam questions were this simple!

Hmm, time of exposure makes sense. Though I have to say, I'm more interested in learning about the science behind sigma phase formation than taking this exam. Where's the fun in that?

Time of exposure definitely seems like the correct answer here. Sigma phase formation is all about time and temperature, not pressure or velocity.

I'm not sure, but I think it could also be C) Stress because stress can also play a role in material susceptibility.
