Abstract:

A method for producing an integral titanium alloy article having at least two regions, each region having a distinct microstructure, which comprises the steps of a providing a suitable mold for the article b introducing a first titanium alloy into a first portion of the mold c introducing a second titanium alloy in powder form into a second portion of the mold and d hot compacting the first and second alloys in the mold to produce a substantially fully dense article. The second alloy may be the hydrided version of the first alloy, or may have a different overall composition from the first alloy, or may be hydrided and have a different overall composition from the first alloy.
