WebFirst, while in a twinned martensitic state, the alloys exhibit a damping potential as a consequence of internal friction which occurs when the material is under load and experiences de-twinning of the martensitic structure [1]. WebDeformation twinning is favoured as a deformation mode, when compared with slip, when: 1. There are few slip systems available, i.e. low symmetry crystal structure e.g. tin …
