List of Metals or Alloys With Fatigue Limits?

Click For Summary
SUMMARY

Steel and titanium are confirmed to have fatigue limits, meaning they can endure cyclic stresses below a certain threshold indefinitely without failure. In contrast, aluminum lacks a fatigue limit, leading to cumulative damage regardless of the force magnitude. The discussion emphasizes the importance of understanding fatigue limits in materials science and references "Physical Metallurgy 4E vol 3" for further exploration of metals and alloys with fatigue limits.

PREREQUISITES
  • Understanding of fatigue limits in materials science
  • Familiarity with the properties of steel and titanium
  • Knowledge of aluminum's mechanical behavior
  • Access to "Physical Metallurgy 4E vol 3" for detailed reference
NEXT STEPS
  • Research the fatigue limits of various alloys beyond steel and titanium
  • Study the mechanical properties of aluminum and its failure modes
  • Explore the concept of cyclic loading and its effects on materials
  • Review case studies on fatigue failure in engineering applications
USEFUL FOR

Materials scientists, mechanical engineers, and anyone involved in the design and analysis of components subjected to cyclic loading 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"?

you can find the answer in Physical Metallurgy 4E vol 3, look under the references in that section of the book for more details.
