Abstract: A method for forming a miniaturized shaped component. Bulk superplastic material is contacted with a flat rotating surface of a rotating tool to frictionally heat the bulk superplastic material with the bulk superplastic material positioned between the flat rotating surface of the tool and a microfabricated tool die. The bulk superplastic material is forced into the microfabricated die once the bulk superplastic material is heated to a temperature between a glass transition temperature and a crystallization temperature.
Abstract translation: 一种形成小型化成形件的方法。 散装超塑性材料与旋转工具的平坦的旋转表面接触，以用位于工具的平坦旋转表面和微加工工具模具之间的体超塑性材料摩擦地加热本体超塑性材料。 一旦将本体超塑性材料加热到玻璃化转变温度和结晶温度之间的温度，则将本体超塑性材料强制进入微加工模具。

Abstract: A shaped metallic component is formed by friction stirring at least a segment 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.
