Which outcome occurs when hydrogen embrittlement affects high-strength steel bolts in offshore wind turbine towers?

💡 Explanation

When atomic hydrogen diffuses into steel, it reduces the steel's ductility and fracture toughness, causing hydrogen embrittlement, therefore promoting crack initiation sites that accelerate fatigue crack growth under cyclic stress. Therefore premature fatigue cracking results, rather than improved ductility, corrosion resistance, or decreased creep, which entail different material properties and mechanisms.
