← ScienceWhich outcome accelerates diffusion-driven hydrogen embrittlement in austenitic stainless steel?
A)Increased yield strength via grain refinement
B)Formation of stress-induced martensite✓
C)Increased chromium content stabilizes passivity
D)Reduced sulfur content decreases diffusivity
💡 Explanation
Formation of stress-induced martensite traps hydrogen via the Cottrell atmosphere mechanism; because trapped hydrogen concentrates at these sites, localized cracking accelerates, therefore, embrittlement advances rather than being mitigated by enhanced yield strength or chromium passivation.
