← ScienceWhich outcome occurs when rapid quenching locks a metallic alloy's crystal lattice structure?
A)Increased resistance strain gradient effects✓
B)Increased dislocation climb towards grain
C)Uniform equilibrium phase transformation
D)Decreased overall materials intrinsic hardness
💡 Explanation
Rapid quenching can freeze dislocations, causing increased resistance from strain gradients because these cannot anneal properly rather than achieving a uniform, equilibrium state. The **generation of a mechanical twin** inhibits dislocation climb; therefore, there's increased resistance due to strain.
