← ScienceWhich outcome results when rapid cooling locks a crystal in a metastable state?
A)Increased residual stress concentrations appear✓
B)Complete crystal structure recrystallization forms
C)Enhanced thermal equilibrium stabilization occur
D)Improved resistance to brittle fracture obtains
💡 Explanation
Increased stress concentrations occur because rapid cooling causes uneven thermal contraction across grains, driving **thermally-induced stress**. Therefore, metastable crystals exhibit significantly more stress, rather than reaching equilibrium or exhibiting complete recrystallization under these conditions.
