← TechnologyWhich consequence results when quenched welding creates martensite?
A)Hydrogen induced cracking is accelerated✓
B)Ferrite grain growth gets inhibited
C)Ductility increases in the weld zone
D)Corrosion resistance improves locally
💡 Explanation
Hydrogen-induced cracking accelerates because *hydrogen diffusion* becomes trapped in the martensite lattice, leading to embrittlement at grain boundaries; therefore, cracking is likely, rather than increased ductility, because martensite is brittle
