Which outcome arises with hydrogen embrittlement under cyclic stress?

💡 Explanation

Under cyclic stress where pre-existing cracks present leading to **stress-induced hydrogen diffusion**: at crack tips weakening atomic bonds and initiating brittle fracture with smaller yield, embrittlement accelerates crack propagation. Therefore, fatigue life lowers, rather than greater strength, corrosion resistance, under tensile action, embrittlement leads to crack nucleation.
