The material with higher stacking fault energy has higher fatigue strength whereas the material with lower stacking fault will have a lower fatigue limit.

The material with higher stacking fault energy has higher fatigue strength whereas the material with lower stacking fault will have a lower fatigue limit. Correct Answer False

The material with high stacking fault energy will easily cross-slip the dislocation, so the slip band formation and gliding are natural. This results in the large plastic zone at the crack tip and the fatigue strength reduces. The material with lower stacking fault energy has higher fatigue strength.
