Abstract: An article made of a medical alloy having two or more alloying elements, and a uniform dispersion of discrete particles, which are substantially free of the two or more alloying elements. A method of making the article includes melting a composition having two or more alloying elements to form an alloy and dispersing a discrete particle in the alloy to form an ingot. The melting and dispersing are performed at a temperature above the alloying temperature of the composition and below the melting temperature of the discrete particle. The ingot is hot worked to form a processed ingot. The processed ingot is cold worked and annealed to form the article.

Abstract: An article having a nickel-titanium alloy and a homogeneous dispersion of discrete particles. The discrete particles are substantially free of nickel and titanium. A method of making the article includes melting a substantially equiatomic composition of nickel and titanium to form an alloy and dispersing a discrete particle in the alloy to form an ingot. The melting and dispersing are performed at a temperature above the alloying temperature of the composition and below the melting temperature of the discrete particle. The ingot is hot worked to form a processed ingot. The processed ingot is cold worked and annealed to form the article.
