← ScienceWhich mechanism causes reduced coercivity in annealed ferromagnetic steel?
A)Grain boundary pinning reduction✓
B)Increased magnetostrictive energy
C)Enhanced crystalline anisotropy
D)Stabilized Bloch wall formation
💡 Explanation
Annealing reduces internal stresses, therefore grain boundary pinning decreases because fewer defects impede domain wall motion. Domains can reverse more easily as grain boundary pinning reduction occurs, rather than an increase in magnetostrictive energy due to stress.
