← ScienceWhich outcome occurs when rapid quenching follows crystal growth?
A)Increased point defect concentration✓
B)Enhanced long-range atomic order
C)Reduced grain boundary concentration
D)Higher elastic modulus throughout lattice
💡 Explanation
Rapid quenching leads to increased point defect concentration because the atoms lack time to arrange into a perfect, long-range ordered crystalline lattice via diffusion; therefore, more vacancies and interstitial atoms form rather than annealing out at equilibrium.
