← TechnologyWhich dimensional consequence arises from localized chilling during die casting?
A)Increased component strain hardening
B)Reduced alloy solidification shrinkage
C)Differential workpiece material distortion✓
D)Elevated surface material blistering
💡 Explanation
Differential chilling induces uneven solidification rates; therefore, stresses cause dimensional distortion rather than uniform shrinkage patterns because the metal contracts differently depending on the cooling rate, and not hardening, blistering, or overall shrinking.
