Wait, are we sure it's not velocity? That seems odd.

Velocity seems off to me; I don't think that's a primary factor. I feel like it's definitely between time of exposure and stress.

I recall a practice question about sigma phase and stress, but I can't remember if it was the main factor or just one of many.

I'm not entirely sure, but I feel like pressure might play a role too. Didn’t we discuss that in relation to phase stability?

I think I remember that time of exposure is really important for phase changes, especially at high temperatures.

Hmm, I'm a bit unsure about this one. I'll need to think through the different options carefully to determine which one best fits the RPA use case.

Hmm, this seems straightforward. I think I'll go with the SQL query activity and the data filter to test and configure the segment.

Time of exposure, no doubt. Though I have to wonder, does sigma phase sound like some kind of metal band to anyone else?

Yeah, time of exposure is key. And haha, sigma phase does sound like it could be a metal band for sure.

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.
