Abstract
Easy-release screw using shape-memory alloy washer for easy recycling of materials has been developed. Products assembled with the screw can be easily disassembled by just heating them up to a preset temperature for opening the washer. This paper experimentally analyzes the opening characteristics of the washer. The results show that the opening temperature strongly depends on the transformation point shape memory alloy and the opening temperature can be controlled by adjusting the heat temperature and processing.
