← ScienceWhich consequence occurs when exposing titanium hydride to extreme temperature?
A)Hydrogen embrittlement induces crack propagation✓
B)Passivation layer prevents further oxidation
C)Lattice expansion eliminates grain boundaries
D)Increased hardness resists plastic deformation
💡 Explanation
Hydrogen embrittlement occurs, because hydrogen atoms diffuse into the titanium lattice therefore weakening the metallic bonds, which induces crack propagation, rather than strengthening it. Hardness might increase at lower temperatures.
