Special microstructures and twin features in $Ti_{50}Ni_{50-x}(Pd,Au)_{x}$ at small hysteresis University of Antwerp
The breaking of symmetry due to atomic displacements in the austenite-martensite phase transformation generally leads to their crystallographic incompatibility. Energy minimizing accommodation mechanisms such as martensite twinning have been recently shown to be a source of hysteresis and irreversible plastic deformation. Compatibility between the two phases can however be achieved by carefully tuning lattice parameters through composition ...
