Question

Which of the following metal is highly susceptible to hydrogen embrittlement?

(a) Titanium

(b) Nickel

(c) Martensitic iron-base alloys

(d) Titanium and martensitic iron-base alloys

This question was posed to me in an interview.

The origin of the question is Eight Forms in chapter Eight Forms of Corrosion of Corrosion Engineering

Answer 1

Right option is (d) Titanium and martensitic iron-base alloys

The best I can explain: Hydrogen embrittlement refers to the brittle cracking failure of reactive metals due to the formation of metal hydrides. Titanium, ferritic, and martensitic iron-base alloys are susceptible to hydrogen embrittlement.
