  • Powder metallurgy titanium alloys
    Patent number: 11008639
    Abstract: A sintered Ti alloy comprising: 4 to 6 wt. % iron; 1 to 4 wt. % aluminium or 1 to 3 wt. % copper; >0 to 0.5 wt. % silicon; >0 to 0.3 wt. % boron; >0 to 1 wt. % lanthanum, and the balance being titanium with incidental impurities. In the associated powder metallurgy formation process, the boron and lanthanum content is preferably introduced into a blended powder mixture in the form of lanthanum boride (LaB6).
    Type: Grant

  • Alloy and method of treating titanium aluminide
    Publication number: 20080041506
    Abstract: A method of treating a titanium aluminide alloy having a single alpha phase field and being capable of producing a massively transformed gamma microstructure by subjecting the alloy to a temperature cycle that produces the massively transformed microstructure having a refined microstructure; the method being characterised in that oxygen securing means are provided within the alloy to prevent diffusion of oxygen to the grain boundary.
