Ultrahigh strain recovery shape memory alloy screen pipe material and preparation method and application thereof

Abstract

An ultrahigh strain recovery shape memory alloy screen pipe material and a preparation method and application thereof. The material is obtained by cold pressing molding of a preform, the preform is prepared by winding a NiTi shape memory alloy wire into a spiral coil and then winding, laying or weaving, the spiral coil of the NiTi shape memory alloy wire in the preform is structurally embedded or interlocked with each other, and the alloy screen pipe material has a recovery strain of 43-83% at a temperature of 100-350° C. The material has excellent high-temperature tolerance, can achieve spontaneous expansion and deformation under high-temperature conditions, and generally has an ultrahigh recoverable strain. Its pore characteristic is a through-hole structure and a pore size is controllable, so that a filtration effect is ensured, and the preparation cost is relatively low.
