Specific alloys, in particular Ni-based alloys, that can be biaxially textured, with a well-developed, single component texture are disclosed. These alloys have a significantly reduced Curie point, which is very desirable from the point of view of superconductivity applications. The biaxially textured alloy substrates also possess greatly enhanced mechanical properties (yield strength, ultimate tensile strength) which are essential for most applications, in particular, superconductors. A method is disclosed for producing complex multicomponent alloys which have the ideal physical properties for specific applications, such as lattice parameter, degree of magnetism and mechanical strength, and which cannot be fabricated in textured form. In addition, a method for making ultra thin biaxially textured substrates with complex compositions is disclosed.

A biaxially textured allow wherein said allow of texture {100}<100>
A biaxially textured alloy wherein said alloy of texture {100}<100>
A biaxially textured allow wherein said allow of texture {100}<100>
A biaxially textured alloy of texture {100}<100>
A method of forming a biaxially textured alloy article of texture {100}<100>, said biaxially textured alloy being characterized by an x-ray diffraction phi scan peak of no more than 30 FWHM, comprising the steps of:
An biaxially textured alloy formed by rolling and annealing containing at least 60 at % of an FCC metal, said alloy having a stacking fault frequency parameter less than 0.01 when deformed to at least 60% deformation without any intermediate anneals.
