Martensitic transformation induced by cooling NiTi wire under various tensile stresses: martensite variant microstructure, textures, recoverable strains and plastic strains

Autor: Tyc, O., Bian, X., Molnárová, O., Kadeřávek, L., Heller, L., Šittner, P.

To understand how martensitic transformation (MT) in polycrystalline NiTi shape memory alloy (SMA) proceeds under external stress, we evaluated recoverable transformation strains and plastic strains generated by the forward MT in nanocrystalline NiTi

Recoverable and plastic strains generated by forward and reverse martensitic transformations under external stress in NiTi SMA wires

Autor: Šittner, P., Iaparova, E., Molnárová, O., Tyc, O., Bian, X., Kadeřávek, L., Heller, L.

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 deforms plastically. Although the alloy demonstrated a very high resistanc

Stress induced martensitic transformation in NiTi at elevated temperatures: martensite variant microstructures, recoverable strains and plastic strains

Autor: Tyc, O., Iaparova, E., Molnárová, O., Heller, L., Šittner, P.

Functional behavior of NiTi shape memory alloys is restricted to temperatures below 150 {\deg}C. To shed light on the origin of the loss of functional properties of NiTi with increasing temperature, we have investigated stress induced martensitic tra
