← TechnologyWhich outcome occurs when a titanium alloy forging cools non-uniformly?
A)Residual stress profile develops✓
B)Accelerated creep rate occurs
C)Enhanced grain boundary diffusion
D)Surface oxide layer disruption
💡 Explanation
A residual stress profile develops because thermal contraction varies locally depending on cooling rates, a process called differential cooling. Therefore, internal stresses are generated rather than uniform contraction, because the heated surface cools faster.
