Abstract
The fatigue properties are studied in detail on the high-tension steel sheets that are used in automobile structures and components. Safety, durability and stability, as well as good press formability for complicated shapes in automobile industries are necessary for this type of steel sheets. The materials used in this study are 4 types of high-tension steel sheets. The materials are designated as A, Q, T1 and T2 in term of as-rolled sheet, direct quench process and different tempering temperature, respectively. The results show that the fatigue limit is at the highest in material A followed by materials T2, T1 and Q. Compared to material A, the surface hardness in all materials are increased and tensile strength are improved in materials Q and T1 but not in T2. Surface fatigue crack initiation and propagation was studied by the replica methods and their morphology was observed by a scanning electron microscope.
