Superelastic Nitinol: The Frontiers of Lifetime Prediction

, 2016
While superelastic Nitinol exhibits only mediocre performance in load-controlled fatigue, its durability in displacement-controlled fatigue is unsurpassed amongst metals. For this reason, it is often used in medical applications in which the native anatomical compliance must be preserved and consequently, where no other metal can survive.
