摘要：A shaped metallic component is formed by friction stirring at least a gment of a single piece of bulk metal to impart superplasticity thereto and thereby yield a single superplastic metal blank from the single piece of bulk metal. The metal blank is then
deformed by a metal deformation process such as forging, rolling, drawing, bending, extruding, gas forming, punching, and stamping.
