A composite structure comprising a body of a superelastic shape memory material and having a surface and having certain physical characteristics including transformation temperature, ductility and tensile strength and recoverable strain and cladding formed of a material covering substantially all of said surface of the body and being in intimate mechanical contact with said surface, said body and said cladding being formed of different materials, said superelastic shape memory material having a recoverable strain in excess of 1.0% and in cross-section of the composite structure forming a major portion thereof, said cladding being formed of a material excluding a shape memory material, said mechanical intimate contact having been formed without substantial diffusion from the material of the cladding into the material of the body so that there is no significant diffusion zone between the material of the cladding and the material of the body so that said certain physical characteristics of the body remain substantially unchanged from their values prior to said intimate mechanical contact.
