← TechnologyWhich consequence results when die mismatch happens during drop forging?
A)Increased flash formation imperfections✓
B)Eutectic transformation microstructure changes
C)Accelerated phase transition propagation
D)Enhanced strain hardening consistency
💡 Explanation
Increased flash formation stems from die mismatch; reduced containment alters material flow during deformation due to plan area shifting. Therefore, higher flash unevenness occurs around the forged portion, rather than uniform flash because symmetrical dies are preferred for homogenous forging.
