This report describes the research performed on single crystals of copper and iron, and polycrystals of copper and iron under fatigue and fretting fatigue loading conditions. The orientation of the crystal has a pronounced effect on the fatigue behavior of both the copper and iron fatigue and fretting fatigue behavior. The introduction of a fretting component produces no degradation of fatigue behavior for either the copper or iron for the conditions studied. However, when fretting is introduced on the polycrystals of copper and iron a serious reduction in fatigue life occurs. The report summarizes the documents generated and the major findings of the research as briefly elucidated above.
