The sheet revealed the tensile strength and elongation of 306 MPa and 34%, respectively, when it was rolled at 250 degrees C and subsequently annealed at 475 degrees C, which exhibits the feasibility of the practical application for autobodies. The observed mechanical properties were explained on the basis of the microstructural characteristics of the alloy sheets.
