Low cycle fatigue behavior and microstructure evolution of a Ni-Cr-W-Mo-based alloy at high-temperatures

Key Points

• Low cycle fatigue behavior was tested at varying high temperatures, showing significant changes in material properties.
• At temperatures above 800 degrees Celsius, the Ni-Cr-W-Mo alloy exhibited a notable decline in fatigue resistance and microstructure degradation.
• Analysis of high-temperature samples highlighted the alloy's microstructural evolution due to cyclic loading over extended periods.
• These findings suggest further research is needed to understand long-term behavior under extreme thermal conditions.
