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

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
w -The corrosion and polarization cbaractistics of zinc have been studied in molar, quiescent solutions of NH&lo,, (NH&SO+, NH&l and NH,Br in the pH range 3.8-5.8. Corrosion rates have been determined by the Tafel line extrapolation procedure and the polarization resistance. method where possible. N
