← ScienceWhich consequence results when hydrogen embrittlement exceeds material tolerance?
A)Reduced tensile strength occurs✓
B)Increased thermal conductivity results
C)Grain boundary lubrication appears
D)Enhanced passive layer formation follows
💡 Explanation
When hydrogen permeates a metal lattice it causes hydrogen embrittlement which lowers fracture toughness because crack initiation occurs along grain boundaries; fracture toughness is linked to tensile strength. Therefore, tensile strength is reduced rather than boundary lubrication or passive layer formation
