List of metals or alloys with fatigue limit

Click For Summary
SUMMARY

Steel and titanium are established metals with defined fatigue limits, allowing them to endure stress below these thresholds indefinitely. In contrast, aluminum lacks a fatigue limit, leading to eventual disintegration under any applied force over time. The discussion emphasizes the importance of understanding fatigue limits in engineering and materials science, suggesting that this concept is critical for selecting appropriate materials in structural applications.

PREREQUISITES
  • Understanding of fatigue limits in materials science
  • Familiarity with mechanical properties of metals
  • Knowledge of engineering principles related to material selection
  • Basic concepts of stress and strain in materials
NEXT STEPS
  • Research the fatigue limits of various alloys, including nickel and cobalt-based alloys
  • Explore the impact of cyclic loading on material performance
  • Learn about fatigue testing methods and standards, such as ASTM E468
  • Investigate the role of microstructure in fatigue resistance of metals
USEFUL FOR

Engineers, materials scientists, and anyone involved in selecting or testing metals and alloys for structural applications will benefit from this discussion.

I know that steel and titanium have fatigue limits.

Just to clarify, metals or alloys with fatigue limits are metals that - as long as they experience pressures that lower than the limits - can last "indefinitely".

Aluminum, for example, does NOT have a fatigue limit. No matter how small the forces, they will add up over time and the aluminum will disintegrate.

I know that some people do not consider fatigue limits to be real, but just assume that it exists for now.

Are there any other types of metals or alloys that can be considered to have "fatigue limits"?

Sounds more of an engineering or material question than chemistry.

True, I will try that sub-forum instead.
