← TechnologyWhich outcome commonly arises when forging processes induce uncontrolled directional stress during deformation?
A)Localized brittle fracture initiation✓
B)Increased elastic deformation capacity
C)Enhanced superficial hardness isotropy
D)Significant grain size homogenization
💡 Explanation
Localized brittle fracture initiates because forging introduces stress concentrations at material discontinuities. This induces crack formation via the Griffith criterion, therefore initiating fracture rather than maintaining elastic deformability because stress exceeds the local cohesive strength. Other options assume uniform stresses.
