This study investigated the tensile and fatigue deformation behaviors of Al-Mn aluminum alloys manufactured by twin roll strip casting process. Al-Mn aluminum alloys (as strip cast(Al 3527K-F, Al 3003-F)) were produced by twin roll strip casting, and heat treated alloy were also examined and compared. Microstructure observation results revealed that Al 3527K-F, H, Al 3003-F, O alloys featured rapid solidification microstructure, in addition, Al 3527K-F, H, Al 3003-F, O alloys were identified to be composed of Al, Al6(Mn, Fe), AlFeMnSi phases. As teat treatment was applied, heat treated alloy formed a more even phase distribution than F alloy. In case of Al 3527K alloy, tensile properties showed that heat treatment resulted in an increase of strength and decrease of elongation. On the other hand, tensile properties of Al 3003 alloy showed that heat treatment resulted in decrease of yield strength, increase of elongation, and similar tensile strengths. High cycle fatigue results showed the Al 3527K-F alloy to have a fatigue limit of 120MPa, and the Al 3527K-H alloy to have that of 145MPa. and then, Al 3003-F alloy has a fatigue limit of 145MPa, and Al 3003-O alloy has a that of 135MPa. As the low cycle fatigue result, Al 3003-O alloy has a superior low cycle fatigue property to Al 3003-F alloy. This study also discussed the tensile and fatigue deformation behaviors of Al-Mn (Al 3527K, Al 3003) aluminum alloys manufactured by twin roll strip casting through the abovementioned mechanical properties as well as the fractographies.
