<p>A method of processing a Ni-Ti-Nb based alloy which contains from about 4 to about 14 atomic percent Nb and in which the ratio of atomic percent Ni to atomic percent Ti is from about 0.8 to 1.2, comprising working the alloy sufficient to impart a textured structure to the alloy, at a temperature below the recrystallisation temperature of the alloy. Preferably, the alloy is worked at least 10 %, by a technique such as rolling or drawing, or another technique which produces a similar crystal structure. The alloy has increased stiffness compared with Ni-Ti binary alloys with superelastic properties.</p> |
