← ScienceWhich consequence results when quenching steel before d-orbital hybridization?
A)Increased formation of austenite grains
B)Reduced hardness and yield strength✓
C)Enhanced susceptibility to hydrogen embrittlement
D)Increased ductile-to-brittle transition temperature
💡 Explanation
Quenching normally hardens steel thanks to martensite formation; however, when halted prematurely, there is incomplete d-orbital hybridization that stabilizes ferrite rather than martensite. Therefore, hardness sharply falls because ferrite is much softer, rather than forming more austenite because quenching usually suppress such structures.
