COIL SPRING HAVING TWO-WAY SHAPE MEMORY EFFECT AND THE FABRICATION METHOD THEREOF, AND ADIABATIC PRODUCT USING THE SAME

摘要

A coil spring having two-way shape memory effect, a fabrication method thereof, and an adiabatic product using the same, which implements two-way shape memory effect by containing precipitates having a certain orientation in a coil spring formed of a shape memory alloy material, and disposes the coil spring having a large displacement difference between below and above transformation temperatures, between two members, thus to provide an adiabatic product having an excellent adiabatic performance and being easy to fabricate.
