    摘要: A process for manufacturing a shaped article that in the manufacturing of a shaped article through preforming of an alloyed hot-dip zinc-plated steel sheet as a starting material and subsequent quenching, would inhibit damaging or detachment of the plating layer at the stage of preforming to thereby enhance the surface quality of the shaped article. The process is characterized by including the first step of providing an alloyed hot-dip zinc-plated steel sheet having a plating layer composed of, by mass, 8 to 25% Fe and the balance Zn, Al and impurities as a starting material, charging the starting material in a first die assembly and carrying out preforming while causing the temperature of the material just before preforming to fall within the range of 41° to 700°C to thereby obtain a preform; the second step of heating the preform at the A-transformation point temperature or above; and the third step of quenching the heated preform from the A-transformation point temperature or above to thereby obtain a shaped article.
