Martensitic transformation induced by cooling NiTi wire under various tensile stresses: martensite variant microstructure, textures, recoverable strains and plastic strains
O. Tyc, X. Bian, O. Molnárová +3
To understand how martensitic transformation (MT) in polycrystalline NiTi shape memory alloy (SMA) proceeds under external stress, we evaluated recoverable transformation strains a…

Recoverable and plastic strains generated by forward and reverse martensitic transformations under external stress in NiTi SMA wires
P. Šittner, E. Iaparova, O. Molnárová +4
Superelastic NiTi 1 shape memory alloy (SMA) wire was subjected to thermomechanical loading tests in tension to evaluate stress and temperature conditions under which the wire defo…

Stress induced martensitic transformation in NiTi at elevated temperatures: martensite variant microstructures, recoverable strains and plastic strains
O. Tyc, E. Iaparova, O. Molnárová +2
Functional behavior of NiTi shape memory alloys is restricted to temperatures below 150 °C. To shed light on the origin of the loss of functional properties of NiTi with increasing…
