← ScienceWhich 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.
