Which consequence results when rapid quenching fixes defects in a crystal lattice?

A)Increased material hardness results.
B)Decreased electrical conductivity occurs.
C)Increased thermal expansion happens.
D)Decreased susceptibility to corrosion results.

💡 Explanation

Increased hardness occurs because rapid quenching introduces dislocations via the mechanism of strain hardening. This impedes dislocation movement, thereby increasing resistance to deformation rather than altering electrical behaviors due to changes in electron mobility.
