Question

Dilute alloying elements of base metals exhibiting a relatively high solubility and diffusivity for atomic oxygen are subject to internal corrosion.

(a) True

(b) False

I had been asked this question during a job interview.

My doubt is from High Temperature Materials in portion High Temperature Corrosion of Corrosion Engineering

Answer 1

The correct answer is (a) True

For explanation I would say: Dilute alloying elements of base metals exhibiting a relatively high solubility and diffusivity for atomic oxygen are subject to internal corrosion. It is due to the formation of preferential stable oxides than the base metals.
