METHOD FOR MAKING TITANIUM-NICKEL ALLOYS, COMPOUND MATERIAL USED THEREIN AND TITANIUM-NICKEL ALLOYS OBTAINED BY THIS METHOD

摘要

A method of making TiNi-alloys having Ni 45 to 60 at % comprises the steps of forming a composite of Ti and Ni material, dimention-reducing and diffusing. The method ables to make the setting and changing of each of the composition ratio very easily and certainly. Further, it can repress the scattering of the composition in the interior of the alloy and the variations of the properties of the product.
