Adaptive hard and tough mechanical response in single-crystal B1 VNx ceramics via control of anion vacancies
A. B. Mei, H. Kindlund, E. Broitman +4
High hardness and toughness are generally considered mutually exclusive properties for single-crystal ceramics. Combining experiments and ab initio molecular dynamics (AIMD) atomis…
Strength, transformation toughening and fracture dynamics of rocksalt-structure Ti1-xAlxN (0 <= x <= 0.75) alloys
D. G. Sangiovanni, F. Tasnadi, L. J. S. Johnson +2
Ab initio-calculated ideal strength and toughness describe the upper limits for mechanical properties attainable in real systems and can, therefore, be used in selection criteria f…
Mechanical properties of VMoNO as a function of oxygen concentration: toward development of hard and tough refractory oxynitrides
Daniel Edström, Davide G. Sangiovanni, Ludvig Landälv +5
Improved toughness is a central goal in the development of wear-resistant refractory ceramic coatings. Extensive theoretical and experimental research has revealed that NaCl struct…
Effects of surface vibrations on interlayer mass-transport: ab initio molecular dynamics investigation of Ti adatom descent pathways and rates from TiN/TiN(001) islands
D. G. Sangiovanni, A. B. Mei, D. Edström +4
We carry out density-functional ab initio molecular dynamics (AIMD) simulations of Ti adatom (Tiad) migration on, and descent from, TiN <100>-faceted epitaxial islands on TiN(001)…
