Plastic Deformation of B19' Martensite: Where it Matters in NiTi Technology
Petr Šittner, Hanuš. Seiner, Petr Sedlák +5
Nitinol technology, besides utilizing the functional thermomechanical properties derived from the B2 cubic to B19' monoclinic martensitic transformation, also exploits the excellen…
Effect of cold rolling strain on the microstructural evolution in equimolar MoNbTaTiZr refractory complex concentrated alloy: Comprehensive characterization
Andrea Skolakova, Haruka Katayama, Pavel Lejcek +8
This work presents a pilot study on a strained complex concentrated alloy based on refractory elements: MoNbTaTiZr. Initially, the as-cast and homogenization-annealed conditions we…

Jan Pinc, Petr Vlcak, Miroslav Lebeda +15
In this research, the influence of the N+ ion implantation process on the microstructure of a biodegradable Zn-0.8Mg-0.2Sr alloy was investigated using various experimental techniq…
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…
