Which consequence results when molten steel undergoes rapid quenching?

A)Increased tensile strength forms martensite
B)Dendritic grain growth increases toughness
C)Austenite phase is uniformly stabilized
D)Lower hardness via bainite transformation

💡 Explanation

Rapid quenching induces the _martensitic transformation_, bypassing equilibrium phase diagrams, because carbon atoms become trapped, distorting the crystal structure; therefore, increased hardness and tensile strength results, rather than softer phases that occur during slow cooling.
