摘要: A method of forming a workpiece (18) comprises: holding the workpiece adjacent a mould (20); using a laser (30) to heat at least a part of the workpiece to a temperature sufficient to induce superplasticity; and applying a fluid pressure to the workpiece, so that it takes the shape of the mould. This has the advantage that the superplastic properties of the material can be used to form the workpiece precisely to the required shape, without needing to heat all of the processing chamber to the superplastic temperature. Before using the laser to heat the workpiece to its superplastic temperature, the laser can be used to heat the whole of the workpiece to a substantially uniform temperature to anneal it. Similarly, after using the laser to superplastically form the workpiece, the laser is used to heat the whole of the workpiece to a substantially uniform temperature to remove any residual stresses. This has the advantage that the whole of the forming can be carried out as a single process, in a single processing apparatus.
