Fatigue Strength
Fatigue strength is defined as the maximum bending stress that a material can withstand without fracture under 10,000,000 cycles of loading, and it is related to the state of the selected material. Under normal circumstances, the fatigue strength is approximately 1/3 of the tensile strength. For solid solution alloys with fine grains, the fatigue strength can be increased to 1/2 of the tensile strength.
