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 region(s) of the article at a temperature greater than the beta-transus temperature of the region(s), while simultaneously heat treating the remaining region(s) of the article at a temperature below the beta-transus temperature of the remaining region(s).
