Here is a good article showing thermal and mechanical fatigue. You can see under moderate mechanical stress, it fails between 1e5 and 1e7 cycles. While that sounds like a lot, consider that there are 3e7 seconds in a year.
So if you had a mechanical device that operated at 1HZ, it would fail in less than a year.

- blincoln 7y agoHow difficult/expensive is it to recycle the material? i.e. if one had some sort of wonder-generator based on it, would it make sense to use a model where once per year, the owner sends the nitinol pieces back to the manufacturer (who recycles them) in exchange for a discount on replacements? I assume since titanium is part of the alloy, just discarding it after use is probably not great from a cost perspective.
