Shape Memory Behavior of an Fe-Mn-Si SMA Spring

A study of Fe-Mn-Si SMA (shape memory alloy) spring indicates that the temperature difference between A-prime(s) - A-prime(f) (the starting temperature of shape memory - the final temperature of shape memory) is as high as 200 C. The recovering force rises continuously as the temperature increases,...

Beschreibung
Zusammenfassung:	A study of Fe-Mn-Si SMA (shape memory alloy) spring indicates that the temperature difference between A-prime(s) - A-prime(f) (the starting temperature of shape memory - the final temperature of shape memory) is as high as 200 C. The recovering force rises continuously as the temperature increases, but its decrease slows as the temperature decreases. The angularity recovery ratio of the spring wire is as high as 66 percent after the training treatment, and the length recovery ratio of the spring is as high as 93. (Author)
