FIELD: metallurgy.
SUBSTANCE: invention relates to manufacturing of products from alloy on the basis of titanium nickelide, mainly of type of thin bars and wire, allowing shape memory effect. Method is implemented in two stages. At the first stage product is heated up to temperature 500-600 °C within 3-10 minutes, then it is implemented straining by tension at a rate not less than 1% and cooling in distorted condition. At the second stage product is heated up to temperature 250±350 °C isolation not more than one minute, repeated straining by tension at a rate not less than 1% and cooling of product with simultaneous loading. Particular method provides straight straightforwardness of product and also high values of pseudoelasticity.
EFFECT: increased mechanical properties and durability of product.
