ABSTRACT:
A Ni--Ti superelastic alloy demonstrates superelastic properties at normal temperatures from about 0 and 30.degree. C. The superelastic alloy allows shape alteration when the temperature is in excess of 40.degree. C. The Ni--Ti superelastic alloy is produced by plastic working a composition containing essentially Ni and Ti, and subjecting the composition to heat treatment at a temperature between 600 and 800.degree. C. to impart shape memory. When the Ni--Ti superelastic alloy is used in an eyeglass frame, it allows the shape of the pad arms to be adjusted at temperatures above about 40.degree. C.
