Which outcome occurs when a hydrogen embrittled pipeline experiences cyclic stress?

💡 Explanation

Hydrogen atoms diffuse to crack tips, because hydrogen embrittlement reduces the energy for crack formation via weakened atomic bonds in the metal lattice, shortening its fatigue life and causing rapid crack growth. Therefore, fatigue crack propagation accelerates, rather than resistance increasing or strength values improving.
