Lately, the severe lattice distortion has been introduced into the body-centered cubic (bcc) Nb–Ta–Ti–V HEA by adding a nearly equal amount of element Zr with a larger atomic radius than other constituent elements through the cast and the subsequent long-term treatment at 1200°C12, and ...
The mixed cluster model was implemented in PDFgui using the spherical shape factor option. The cluster diameter was used as a fitting parameter, producing the best fits in the range of 5–20 Å. The BCC and FCC cells are randomly populated by all six elements in the alloy, with lattice...

The arrangement of the crystalenables the atoms to be most closely packed with maximum amount of primary bonds andminimal energy of the aggregates; it is for this reason that the atoms are arranged in such away.b)The first type of crystal structure exhibited by metals is the BCC (Body ...
