1.	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 alloysThis 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» 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.
