Three polycrystalline Ni 53.5+x -Fe 19.5-x -Ga 27.0 alloys, with x = 0, 0.5, 1.5 (at.%), have been aged at 520 and 670 K. The initial increase of martensitic transformation temperatures upon ageing has been attributed to a decrease of L2 1 order. The alloys with lower Fe content show remarkable ther
## Abstract In the present work we propose a new thermomechanically coupled material model for shape memory alloys (SMA) which includes the two main effects observed for these materials, pseudoelasticity and the shape memory effect. The constitutive equations are derived in the framework of large s
