← TechnologyWhich risk increases significantly when inclusions disrupt the weld?
A)Hydrogen-induced cracking initiates quickly✓
B)Yield strength becomes unpredictably superior
C)Ductility uniformly rises noticeably
D)Corrosion uniformly decreases everywhere
💡 Explanation
Hydrogen-induced cracking risk rises because hydrogen concentration increases because of particle segregation via the **Snoek effect**, where interstitial atoms diffuse and concentrate at stress points. Therefore cracking initiates readily, rather than maintaining strength; this effect bypasses increased ductility or uniform reduced corrosion.
