Abstract: Disclosed herein is a superelastic alloy comprising tin, in an amount of between 1 at. % and 8 at. %, niobium, in an amount of between 1 at. % and 10 at. % and iron, in an amount of between 0.5 at. % and 3 at. %. The alloy may also optionally comprise oxygen, in an amount of between 0 and 2 at. % and zirconium, in an amount of between 0 and 10 at. %. The balance of the alloy composition is titanium and unavoidable impurities.

Abstract: A method for producing a metal structure comprising a porous inter-dendritic matrix defining a network of dendritic channels, the method comprising the steps of: preparing an alloy melt comprising a metal element and at least one alloying element, cooling the alloy melt to a solid alloy, wherein the cooling promotes formation of a network of dendrites rich in the at least one alloying element within an inter-dendritic matrix rich in the metal, dealloying the solid alloy to remove alloying element from the dendrites and the inter-dendritic matrix to obtain the metal structure.

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).

Abstract: Zirconium sponge can be chemically depassivated by treatment with hydrofluoric acid to improve the ability of molten magnesium/magnesium alloy to dissolve zirconium from the treated zirconium sponge and to form a melt containing substantially evenly distributed particles of zirconium. Optical micrographs showing the grain refining ability of pretreated sponge when added to pure magnesium at 680° C. All micrographs are of the same magnification. (a) Pure magnesium, (b) after adding 1 wt % sponge followed by 20 minutes manual stirring, and (c) after a further 10 minutes stirring.
