While the small-strain shear modulus G max has been discussed by Wichtmann and Triantafyllidis [1] the present paper focusses on P-wave velocity v P, on the small-strain constrained elastic modulus M max and on Poisson's ratio 谓. It is demonstrated that while v P and M max do not...
The MAX phases with a three-dimensional structure are generally represented with the formula of Mn+1AXn (n = 1–3), where M stands for an early transition metal, A indicates A-group element (IIIA or IVA), and X is carbon and/or nitrogen elements. Show abstract Elastic anisotropies, ...
MAX phase materials (with general formula Mn+1AXnn = 1–3) are the transition metal ternary carbides and nitrides, which provides the bridge between metals and ceramics in terms of properties, and have been attracted significant attention of the scientific community since they were discovered1...

The MAX phases with chemical formula Mn+1AXn, where M is a transition metal, A is an A-group element, and X is C or N and n varies from 1 to 3, discovered by NOWOTNY [1], have recently attracted the interest of both material scientists and physicists due to their astonishing combina...
