摘要：
PROBLEM TO BE SOLVED: To provide a superelastic molding method capable of making the plate thickness distribution of a molding optimum. SOLUTION: By mutually welding the rims of a thick raw plate 1a and thin raw plates 12b, 13b, a tailored blank 1 is formed, and it is clamped with a female mold 402 and a block 403. When a pressure is applied to the tailored blank 1 at the predetermined temperature, the raw plate 1a is subjected to superelastic deformation to be stretched, and pushed to the bottom face 4022 of the female mold 402. Thereby, a bead with a thick bottom can be manufactured.
