← ScienceDuring rapid metal quenching, which defect results when thermal energy minimizes grain boundary movement?
A)Increased residual stress✓
B)Enhanced creep resistance
C)Improved surface hardness
D)Decreased thermal expansion
💡 Explanation
Increased residual stress occurs because rapid quenching hinders complete Atomic diffusion, a mechanism where atoms arrange into stable configurations during annealing; therefore stress remains embedded, rather than being relieved fully through equilibrium.
