The mechanisms of the transformations 5 + p in a silver-zinc alloy of 49.97 at.% silver have been investigated by means of electrical resistivity measurements. Values obtained at various rates of heating and cooling in the temperature range 21O"C-340Β°C are given. The transformation 5 -+ B takes plac

Neutron diffraction studies of three alloys in the /Y-phase field of the Cu-Zn system were carried out in order to evaluate the Bragg-Williams long range order parameters. From these, configurational entropies of mixing were obtained and combined with previously published values of total entropies o
The dew-point technique has been used to determine vapour pressures, and hence thermodynamic properties, of liquid alloys of zinc and copper over a wide range of composition. Results indicate positive deviation from ideality of the zinc activity in the composition range 0.70 to 1.00 Nz,. Fluctuation
The structures and transformations which occur in the silver-zinc alloys of around 50 at. per cent composition are reviewed. The crystallographic relations in the 8' and 4 phases are examined. It is shown that the @' + 5 transformation may be brought about by an interchange of nearest neighbour sil
