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…
In-situ observation of elastic instability of stress-induced B19 martensite in thin NiTi wires
Petr Sedlák, Miroslav Frost, Martin Å evÄÃk +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 Å evÄÃk +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…
Scanning acoustic microscopy characterization of cold sprayed coatings deposited on grooved substrates
Martin Koller, Jan Cizek, Michaela Janovská +4
The effect of non-planar substrate surface on homogeneity and quality of cold sprayed (CS) deposits was studied by scanning acoustic microscopy (SAM). Fe coatings were cold sprayed…
