Bending Fatigue Behaviour of Cu-Al-Mn Shape Memory Alloy

The purpose of this study is to investigate fatigue characteristics of Cu-Al-Mn superelastic alloy for lumbago prevent apron and assistance tools for grape faming. The specimen was made from  Cu-Al-Mn superelastic wires of 1.8mm in diameter and 530mm in length. Specimens were made by Furukawa Techno Material Co., Ltd. The apparatus generated the power to use superelastic component. The transformation temperatures were measured by differential scanning calorimetry (DSC). The bending fatigue characteristics of superelastic components were investigated by fatigue tester. The maximum strain ration of bending fatigue test was about 3%. Fatigue lives of the superelastic components were about 3,000 times.
