Which outcome occurs when exceeding the recommended quenching time after forging with martensitic steel?

A)Austenite grain boundary embrittlement arises
B)Increased retained austenite transformation occurs
C)Carbon segregation during beta transformation
D)Decreased compressive residual tensile stresses

💡 Explanation

Exceeding quenching time embrittles grain boundaries because continuous cooling introduces localized segregation and carbide precipitation. Therefore, embrittlement occurs rather than transformation because extended time diminishes the solution strengthening effect.
