Low Cycle Fatigue Behavior of Heat‐Resistant Austenitic Cast Steels at 950 °C

Exhaust manifolds are frequently subjected to severe thermal cycling due to startup and shutdown of automobile engines; consequently, high‐temperature fatigue is the predominant failure mode for these components. The research about the relationship between high‐temperature fatigue properties and as‐...
