The intrinsic stacking fault density (a) has been calculated from X-ray peak shift measurements on filings of solid solutions baaed on Cu, Ag and Ni and on Pb and Al, respectively at room temperature and in liquid air. The increase of a with solute content (p) is the sharper the larger the valency o

Diffusion coefficients of iron, cobalt and nickel in silver have been determined over the temperature range 6006850Β°C using radioactive tracers and the residual-activity technique. The results are as follows (in units of cm2/sec): DFe/ag = 9.4 x lo-' exp (-29,6OO/RT) DCo,Ag = 3.0 x IO-' exp (-29,70O
Anodic dissolution of milligram amounts of the sample and removal of most of the dissolved silver are done simultaneously by electrolysis using the sample as anode, a platinum cathode controlled at -0.25 V vs. SCE and 1 ml of 0.08 M nitric acid-O.001 M sutphuric acid as electrolyte. Silver remaining
