The triclinic high temperature modification of the α phase of the Zn–Al system

The structure of the β phase of the Zn–Al system was reinvestigated. The X-ray diffraction (XRD) pattern of the Zn–21.8wt%Al after 9 h at 350°C clearly showed the splitting of some Bragg peaks. The triclinic structure permits a description of the spectra with a = 285.857, b = 285.283, c = 285.847 pm...

Description
Summary:The structure of the β phase of the Zn–Al system was reinvestigated. The X-ray diffraction (XRD) pattern of the Zn–21.8wt%Al after 9 h at 350°C clearly showed the splitting of some Bragg peaks. The triclinic structure permits a description of the spectra with a = 285.857, b = 285.283, c = 285.847 pm, α = 59.602°, β = 59.869°, γ = 59.716°. This structure corresponds to a small distortion of the primitive R cell of the high temperature fcc solid solution α-(Al) when the Zn content reaches about 69.5 wt% at 350°C.
