Abstract Scope |
Superelastic metastable β Ti alloys display hysteretic loading behaviour by exploiting a reversible martensitic transformation. This can be used to harvest waste mechanical energy or dissipate the energy of vibrations. However, the application of these materials is currently limited by a degradation in mechanical performance which occurs rapidly within a few load cycles.
Historical attempts at stabilising the transformation behaviour have focussed on superelastic training, whereby pre-cycling can generate a more consistent mechanical response. Unfortunately, this has the effect of significantly decreasing the hysteretic response of the material, which is undesirable in energy harvesting or vibration damping applications.
Instead, this work demonstrates a new way by which a more consistent transformation response can be achieved and gives an insight into the understanding of the transformation behaviour of this class of alloy. |
