Metal dusting? More like metal busting! Am I right, folks? Haha, someone call the metallurgy humor police!

I'm scratching my head on this one. 'None of the above' seems like the safest bet, but I'm not totally confident.

I'm going with graphitization. Sounds like the metal is turning into graphite, which would definitely cause some rapid wastage.

No way, it's gotta be decarburization. That's when the carbon gets stripped out of the metal, leading to all sorts of issues.

So, it's important to monitor and prevent decarburization to avoid metal dusting issues.

I've seen it happen before, decarburization can really cause some serious damage.

Yeah, decarburization weakens the metal and makes it more susceptible to rapid wastage.

I think you're right, decarburization is definitely a precursor to metal dusting.

Hmm, I think it's got to be carburization. That's when the metal gets saturated with carbon, right?

I'm not sure, but I think it could also be B) Carburization. It involves carbon diffusion into the metal.
