← ScienceWhich consequence results when increased hydrogen permeation occurs?
A)Hydrogen embrittlement reduces tensile strength✓
B)Increased thermal conductivity resists fatigue
C)Matrix toughness avoids creep damage
D)Improved ductility prevents edge dislocations
💡 Explanation
Hydrogen embrittlement occurs because, under stress, hydrogen atoms accumulating at grain boundaries results in fracture via crack propagation, therefore strength lowers rather than increases because alternative changes act differently.
