Abstract
A process for the production of a superelastic material out of a nickel and titanium alloy, characterized by the fact that it consists in obtaining an ingot starting from a mixing of nickel and titanium consisting in 55.6%.+-.0.4% in weight of nickel and to proceed with a thermal treatment of martensite plaquettes generation by subjecting said ingot during 5 to 45 minutes to a temperature comprised between 480 and 520.degree. C. The process allows the obtaining of a truly superelastic material at room temperature.
Claims21
A process for the production of a superelastic material made out of a nickel and titanium alloy comprising the steps of:
- a) providing a workpiece of a mixture of nickel and titanium consisting of 55.6%.+-.0.4% in weight nickel and the balance substantially titanium, and
- b) subjecting the workpiece to a thermal treatment at temperatures between approximately 400 and 520.degree. C. for a period of approximately 5 to 60 minutes to thereby generate martensite platelets within the workpiece and thereby form a material which is superelastic.
