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.
