Brillouin Zone Effects in Aluminium Alloys

Article metrics


IN experiments on the solid solutions of zinc in aluminium, it has been found that there are marked deviations from Vegard's law in alloys containing less than 25 atomic per cent zinc. The deviations of the lattice spacing/composition curve from a straight line are a maximum at 16·5 atomic per cent zinc, coincident with the formation of the α'-phase at 275° C. Further, when the α'-phase is formed, the lattice spacing of the α-phase remains constant over the composition range 16·5–25 atomic per cent zinc and the corresponding temperature change from 275° to 315° C.
