Abstract

Fatigue characteristics of aluminum cast alloy AC2B-T6 with cast skin S. Ohamal, T. yoshimura2 & H. ~ o ~ u c h i ~ 1 Graduate School of Engineering, Kyushu University, Japan 2 Faculty of Engineering, Kyushu University, Japan Abstract Recently, aluminum cast alloy has been used for the parts of a car, for example a cylinder head or a housing, because of the high specific strength and easy processing. It receives stress amplitudes of more than 10' times in the used period. So, the fatigue characteristics need to be understood clearly to endure in the used environment. But a lot of studies of aluminum cast alloy with a cast skin have not been carried out because of a complicated shape. So the present authors researched the fatigue characteristics of the aluminum cast alloy with a cast skin, AC2B-T6 supplied by TOYOTA Motor Co in Japan. The tensile strength is 381[MPa] and Vickers hardness is 151. The plane bending fatigue test was carried out with a Schenck test machine. The specimen surface was
