Aug 01,2005·Grain size variation gives rise to a longer fatigue life compared with a structure with equal grains.One possible explanation is that even if the crack starts in a large grain and grows fast there,the next grains is probably smaller than in a structure of equally sized grains,and therefore,it grows slower in the second grain.
