Study of the acoustic and thermal response of an elastically anisotropic solid to a sub-nanosecond laser pulse in transient grating spectroscopy
Jakub Kušnír, Tomáš Grabec, Petr Sedlák +2
Transient grating spectroscopy (TGS) is a material characterization technique based on laser-induced thermoelastic excitation of thermal and acoustic gratings. On opaque samples, t…
Magneto-elastic softening in cold-sprayed polycrystalline nickel studied by resonant ultrasound spectroscopy
Michaela Janovská, Petr Sedlák, Martin Ševčík +5
Cold-sprayed metallic deposits are additively manufactured materials containing high levels of compressive residual stress. Here we show that the presence and intensity of this str…
In-situ observation of elastic instability of stress-induced B19 martensite in thin NiTi wires
Petr Sedlák, Miroslav Frost, Martin Ševčík +2
A laser-ultrasonic approach was used to measure elastic properties of a superelastic nickel-titanium wire with the aim to evaluate their evolution with stress and temperature in st…
Elastic constants of single-crystalline NiTi studied by resonant ultrasound spectroscopy
Lucie Bodnárová, Michaela Janovská, Martin Ševčík +6
Contactless, laser-based resonant ultrasound spectroscopy was utilized to monitor changes in elastic properties in single-crystalline NiTi shape memory alloy. It was observed that…
