Abstract

The crystal structures of elements and alloy phases in the B-metal region (B2(Zn) to B5(As) groups) have been classified into phase fields determined by their position in the periodic table. The limited number of equilibrium phases with element-like, disordered crystal structures and of extended terminal solid solutions has been more than doubled by the addition of metastable phases produced by ultra-rapid quenching from the melt (splat cooling). Strong structural correlations exist. Some high pressure phases have been included; in some cases, a qualitative discussion from the viewpoint of pseudopotential theory is given.
