Electron-microscopic evidence for heavy faulting in silver-germanium alloys on rapid solidification
(1970) P. Furrer; T.R. Anantharaman; H. Warlimont
Silver-germanium alloys of five different compositions in the range 5-22 at. % Ge were quenched from the melt by the gun technique and immediately subjected to transmission electron-microscopic examination. The observations confirm earlier x-ray evidence for light to heavy random faulting in both f.c.c. and h.c.p. phases on solidification. There is also evidence for formation of close-packed structures with regular long-period stacking sequences (up to 24 layers) and random stacking faults in alloys containing 10-22 at. % Ge. The quenched foils are found to have a generally random orientation of grains, even in sections having extremely fine grains (less than 500 A). © 1970 Taylor & Francis Group, LLC.
