← TechnologyAfter forging, which issue arises when annealing is improperly controlled?
A)Grain growth lowers strength✓
B)Increased hardness promotes ductility
C)Residual tensile stress reduces brittleness
D)Work hardening increases fatigue life
💡 Explanation
When annealing forged parts, uncontrolled temperature or duration causes grain growth, because the atoms gain mobility and coalesce, therefore reducing material yield strength, rather than achieving desired stress relief or refined microstructure.
