Method: HCF, ASTM E466-15, 10 million cycles, fully reversed Aluminum alloys do not have fatigue limit. Actual fatigue values depend on sample geometry and specially surface finish. EOS uses machined (turned) samples in determining material properties. Typically EOS T6 heat treatment does not have significant effect on fatigue strength.
