← TechnologyWhich distortion occurs when asymmetrical cooling follows forging?
A)Residual stress concentration emerges✓
B)Galling from surface adhesion occurs
C)Work hardening reaches saturation
D)Delta ferrite percentage increases
💡 Explanation
Uneven cooling creates a temperature gradient, and then thermal stresses, so the mechanism is **differential contraction** causing residual stress concentration because the material shrinks at varying rates. Therefore, internal stress results, rather than surface galling, work hardening, or phase changes.
