| Abstract: | Structural relationships between Mo2BC, σ-MoB, β-MoB, and β-MoC1?x are described and possibilities for planar intergrowth defects (Wadsley defects) and nonstoichiometry are considered. The term chemical stacking fault is proposed. Electron microscopy of Mo2BC specimens revealed crystals that were rich in planar defects with widths consistent with the defects postulated. |
