ABSTRACT:
A method of superplastic forming of titanium packs and an associated assembly is provided. The titanium packs can include sheets having different granular structures so that the different sheets are adapted to superplastically form at different temperatures. One or more of the sheets can be formed at a temperature that is below the superplastic forming temperature of another sheet in the pack. In some cases, the occurrence of markoff can be reduced or eliminated.
