Peculiarities of Implementation of Abnormally High Shape Memory Effects in Thermomechanically Treated Ti-Ni Alloys

摘要

The combined action of a number of factors (the initial phase state, structure state, and parameters of the external actions) by their simultaneous variation upon induction of the shape memory effect (SME) and the two-way SME (TWSME) in the Ti-50.7 at % Ni alloy on the functional characteristics during bending is studied. The obtained values of the recoverable strain ε_r= 14.8% and ε_(rw) = 5.4% substantially exceed the earlier reached level of the SME and TWSME parameters in binary alloys.
