Isothermal martensitic transformation in metamagnetic shape memory alloys
We show that in metamagnetic shape memory alloys exhibiting a magnetostructural first order phase transition the direct transition from ferromagnetic austenite to nonmagnetic martensite is isothermal. In contrast to the direct transformation, the reverse one nonmagnetic martensite–ferromagnetic austenite is athermal, just as are athermal both direct and reverse martensitic transformations in co...

متن کاملPhase-field modeling of martensitic microstructure in NiTi shape memory alloys
A phase-field model is developed to study the cubic to monoclinic martensitic phase transformation in nickel–titanium (NiTi) shape memory alloys. Three-dimensional phase-field simulations show the nucleation and growth of monoclinic B190 multivariants that form a polytwinned martensitic microstructure. Parametric studies demonstrate that mechanical constraints and crystallographic orientation g...
متن کاملEnergy landscape for martensitic phase transformation in shape memory NiTi
First-principles calculations are presented for parent B2 phase and martensitic B19 and B190 phases in NiTi. The results indicate that both B19 and B190 are energetically more stable than the parent B2 phase. By means of ab initio density functional theory, the complete distortion–shuffle energy landscape associated with B2? B19 transformation in NiTi is then determined. In addition to accounti...
متن کاملDamping Properties of Shape Memory Alloys During Phase Transformation
A high damping capacity is considered as one of the important functional properties of shape memory alloys. Those properties are related to a thermoelastic martensitic transformation. As a consequence of this transformation, the internal friction or damping can be investigated for three different states: 1. during thermal transformation cycling, 2. during martensite induced strain cycling at co...
