• Torsional fatigue tests were conducted on plain and pre-cracked specimens with different combinations of the stress axis and the anisotropy direction. The fatigue behavior was observed microscopically as well as macroscopically. For the plain specimen, anisotropy was observed in total fatigue lives which was caused by the difference of microscopic fatigue process due to laminated structures and inclusions. However, no anisotropy was found either in slip band formation at an early stage of fatigue process or in macroscopic appearances of fatigue-failured specimens. For the cracked specimens in which band structures ran parallel to one of the principal stress axes. Effect of inclusions on macroscopic fatigue process was found more remarkable for the plain specimens than the pre-cracked specimens.
