← ScienceWhich consequence results when dissolved hydrogen gas destabilizes titanium alloys?
A)Hydride formation embrittles metal structure✓
B)Oxidation accelerates causing uniform corrosion
C)Passive layer reforms with greater strength
D)Grain boundaries become increasingly passivated
💡 Explanation
Hydrogen induces embrittlement using the mechanism of hydride formation; dissolved hydrogen reacts with titanium to create brittle titanium hydride precipitates, therefore toughness drops sharply rather than the metal exhibiting normal corrosion because a hydride phase predominates.
