title: [Characterizing of parameters of shape memory and elasticity of nickel-titanium wires by electro thermal influence].
abstract: Optimal parameters of electro thermal influence on nickel-titanium wires for giving them new shape (bends) without losing basic physical properties - shape memory, elasticity are determined in terms of clinic. It is confirmed that by thermal influence of electric current on nickel-titanium wires it's possible to achieve new shape without changing the parameters of elasticity. Optimal parameters of continuous current intensity (strength) and interaction time are determined for: Nitinol 0.016, 0.016 x 0.022, NeoSentalloy 0.016 x 0.022 (GAC International, Inc). It was established that during heat treatment of nickel-titanium arch wires the shape of wire changes earlier than the elasticity.
