Brittle fracture, huh? Sounds like my high school relationship. Maybe they should do some impact testing on that too.

I'm surprised they didn't include an answer about welding procedure qualifications. That's the real key to avoiding brittle fracture, isn't it?

Haha, D is just plain wrong. Tensile strength has nothing to do with brittle fracture. Clearly the correct answer is C.

Hmm, I was thinking B, ductility. But I guess toughness is more specific to resisting brittle fracture. Good catch!

I'm not sure, but I think it's important to consider both yield strength and toughness in weldments.

I think the answer is C. Toughness is the key property that prevents brittle fracture in weldments at low temperatures.
