Fig. 9: Interfacial elastic strain energy density as a function of its normal vector.

Spherical plots of \(B(\overrightarrow{n})\) for a flat and coherent interface (a) general three-dimensional view with gradient colors representing the values in GPa (note that some level of transparency is applied to the \(B(\overrightarrow{n})\) surface in order to highlight the minimum values). Black arrows represent two instances of directions that minimize the interfacial coherency strain energy density, \(\overrightarrow{{n}_{0}}\). b Polar plot of \(B(\overrightarrow{n})\) projected on the (001)β plane with \(\overrightarrow{{n}_{0}}\) represented with blue arrows. c Same as (a) but viewed from the [010]β direction (red arrows) and zoomed on the minimum points.
