Abstract
The static and dynamic mechanical behavior of coil spring made of a Cu-26wt%Zn-4wt%Al alloy which undergoes thermoelastic martensite transformation at 19°C have been studied by means of load-elongation curve and transfer function measurements. The pseudeoelastic behavior, such as superelasticity and ferroelasticity, has been observed during cooling and heating. A well-defined internal friction peak was found at around room temperature and the application of the alloy for self-damped spring was proposed and discussed.
