← HistoryWhich destructive outcome results from insufficient cooling during forced carburization?
A)Catastrophic loss carbon structural integrity
B)Complete embrittlement component fracture resistance✓
C)Superficial phase transformation hardening distortion
D)Uniform carbon infiltration depth uniformity
💡 Explanation
Component embrittlement occurs because the diffusion of carbon during carburization forms brittle iron carbides. The failure happens through phase transformation at high temperatures thereby reducing fracture resistance rather than creating uniform hardening. Instead uniform cooling manages carbides therefore reduces embrittlement.
