A correlation of structural changes with nanomechanical properties in TiN-AlN multilayer films
Nidhin George Mathews, Aidan A. Taylor, Johannes Zechner +5
The present work investigates the changes in overall nanomechanical properties of reactively sputtered TiN-AlN multilayer films arising due to phase transformation in the AlN layer…
Microscale bending plasticity and fracture behavior of amorphous aluminum oxide films
Nidhin George Mathews, Erkka J. Frankberg, Vivek Devulapalli +12
Recent work has demonstrated microscale compressive plasticity in pulse laser deposited (PLD) amorphous alumina (a-Al2O3). This work explores microscale bending plasticity and frac…
The effect of elastic-plastic mismatch and interface proximity on the fracture toughness of Ti-TiN thin films
Nidhin George Mathews, Aloshious Lambai, Marcus Hans +3
Magnetron sputtered titanium nitride (TiN) thin films are widely used as protective coatings due to their high hardness, but suffer from inherent brittleness and low fracture tough…
Deformation and adiabatic heating of single crystalline and nanocrystalline Ni micropillars at high strain rates
Nidhin George Mathews, Matti Lindroos, Johann Michler +1
The deformation behavior of single crystal and nanocrystalline nickel were studied using in situ micropillar compression experiments from quasi-static to high strain rates up to 10…
