Crystal planes and directions
WebMar 7, 2011 · The viewer not only allows studying the symmetry of specific planes, but also visualizes the density of the atoms in certain directions. This is important for a process called channeling (see the Wikipedia entry ). In this case a (high-energy) atom or ion penetrates the crystal. If the atoms of the crystal have a low density in the direction of ... WebParsing the effect of slip-twin interactions on the strain rate and thermal sensitivities of Magnesium (Mg) alloys has been a challenging endeavor for scientists preoccupied with the mechanical behavior of hexagonal close-packed alloys, especially those with great latent economic potential such as Mg. One of the main barriers is the travail entailed in fitting …
