NITINOL-Based Fuze Arming Component

Abstract

NITINOL Shape Memory Alloy wire was strained to increase its first-time transformation temperature to as high as 150 deg C. The useful work done by a wire, within limits, is a function of the strain in it. Strains residual from the annealing process and those introduced after annealing can greatly affect the time transformation. The load lifted and extent of contraction can be varied inversely for a given wire. The energy required for heating and transformation was a function of the work performed, varying between 60 and 144 Joules per gram for the 1/4 mm (0.010 inch) wire used in this work. It is concluded that NITINOL can be used for Safing and Arming components. Under no-load conditions NITINOL can recover 6.5 percent stain at 360 C. Keywords: Fuze; Safing and Arming; Shape memory alloys; Nickel alloys; Titanium alloys.
