摘要：
A method of correcting the shape of a brittle cast component such as a low pressure turbine blade. The method includes steps of placing the component against a creep mould having a surface defining the desired profile of the component and HIP treating it to creep deform the component to the desired shape whilst consolidating it and removing gas and shrinkage porosity.
