Which consequence occurs when dissolved hydrogen exceeds the solubility limit in high-strength steel?

💡 Explanation

Hydrogen embrittlement results because hydrogen atoms diffuse to grain boundaries; this mechanism facilitates premature crack formation and propagation, therefore reduces fracture toughness rather than increasing resistance or stress intensity; different alloying would alter hydrogen diffusion.
