Battery Actuation of NITINOL at Sub-Zero Temperatures
Abstract
It is feasible to use batteries to produce rapid shape memory response in NITINOL wires which are in sub-zero temperature ambients. Data are presented on lithium thionyl chloride batteries used to joule heat 10 mil diameter wires of nominal transformation temperatures of 90-105 deg C. The batteries and wires were jointly tested in a -35 deg C ambient air environment. The wire contracted 5 percent in length (0.4 inch) and lifted a 1 pound load in 1/2 second. Keywords: NITINOL; Fuze; Safing and arming; Shape memory alloys; NiTi.
