← TechnologyWhich consequence results when rapid quenching follows alloy forging?
A)Martensite formation and increased brittleness✓
B)Austenite retention and improved ductility
C)Ferrite precipitation and reduced hardness
D)Pearlite transformation and increased toughness
💡 Explanation
Martensite forms because the rapid cooling prevents equilibrium phase transformations, therefore the material hardens with higher brittleness, rather than reaching softer, more ductile states achievable with slower cooling rates.
