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…
Duality of Wave Modulation and Nanotwinning in Ni-Mn-Ga Martensite via Long-Period Commensurate States
P. VeÅtát, M. Zelený, A. Sozinov +8
Structural modulation is a key ingredient behind the extraordinary (magneto)elastic response of Ni-Mn-Ga martensite, yet its link to fine microstructural features and twin-boundary…
Anomalous thermal and elastic properties of an epitaxial NiTi film exhibiting R-phase
Kristýna RepÄek, Tomáš Grabec, David MareÅ¡ +8
Shape memory alloys like NiTi are at the core of emerging thermal management applications, including elastocaloric refrigeration, thermoelastic harvesting, and latent heat storage.…
On the proposed concept of mechanical phasons in Ni-Mn-Ga modulated martensite
Petr Sedlák, Tomáš Grabec, Hanuš Seiner
We discuss modulation phasons as a possible source of unusual elastic behavior of five-layer modulated (10\,M) martensite of the Ni-Mn-Ga shape memory alloy. This material exhibits…
Ultra-transient grating spectroscopy for visualization of surface acoustics
Tomáš Grabec, Pavla Stoklasová, Kristýna RepÄek +5
Ultrasonic wave propagation across material surfaces reveals essential information about the materials' elastic behavior. The elastodynamic response of the surface is characterized…
