Which outcome occurs when cooling molten steel too rapidly?

A)Undesirable martensite phase transformation occurs
B)Austenite grains become excessively large
C)Dendritic growth is completely suppressed
D)Equilibrium phases shift towards ferrite

💡 Explanation

Rapid conduction quenches the steel before pearlite formation; shear stress causes diffusionless Martensite transformation to occur, because carbon atoms are trapped. Therefore, Martensite happens rather than bainite, and this requires specific high-cooling-rate conditions.
