← ScienceWhich outcome occurs when applying continuous laser ablation to a titanium alloy?
A)Formation of a heat-affected zone✓
B)Elimination of all surface defects
C)Increased material ductility overall
D)Reduced thermal conductivity properties
💡 Explanation
A heat-affected zone forms because laser ablation involves rapid heating and cooling, inducing thermal stresses. Therefore, the zone appears where microstructural alteration occurs, rather than defect elimination, because high temperatures exceed the phase transition threshold. This contrasts with ductility enhancement or conductivity alteration.
