Enhancing plasticity in high-entropy refractory ceramics via tailoring valence electron concentration
Davide G. Sangiovanni, William Mellor, Tyler Harrington +2
Bottom-up design of high-entropy ceramics is a promising approach for realizing materials with unique combination of high hardness and fracture-resistance at elevated temperature.…
Temperature-dependent elastic properties of binary and multicomponent high-entropy refractory carbides
D. G. Sangiovanni, F. Tasnádi, T. Harrington +2
Available information concerning the elastic moduli of refractory carbides at temperatures (T) of relevance for practical applications is sparse and/or inconsistent. We carry out a…
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…
First principles characterization of reversible martensitic transformations
Alberto Ferrari, Davide G. Sangiovanni, Jutta Rogal +1
Reversible martensitic transformations (MTs) are the origin of many fascinating phenomena, including the famous shape memory effect. In this work, we present a fully ab initio proc…
