Abstract:
A method for producing an integral titanium alloy article having at least two regions, each region having a distinct microstructure is provided. The method comprises heat treating one or more selected regions of the article at a temperature greater than the beta-transus temperature of the regions, while simultaneously heat treating the remaining regions of the article at a temperature below the beta-transus temperature of the remaining regions.
