DIFFUSION MECHANISMS IN ORDERED BODY-CENTERED CUBIC ALLOYS \* P. WYNBLATTT Celculetions of defect migration energies by three different mechanisms are presented. The mechanisms considered were: cyclic vacancy motion by a correlated set of six nearest-neighbor jumps, next-nearest-neighbor vacancy jum

โฆ Synopsis
Diffusion coefficients for "*Ti and "*V in titanium-vanadium alloys were determined at 10 wt.?; increments in the temperature range of 900ยฐC to within about 50ยฐC of the melting points. The data 8re adequately described by continuously curved lines on Arrhenius-type plots.
SELF-DIFFUSION DANS LES ALLIAGES CUBIQUES
A CORPS CENTRE DE TITANE-VANADIUM Les suteurs ont determine les coefbcients de diffusion du *'Ti et 4aV dens une s&e d'alliages Titane-V8nadium pour des concentrations en poids croiss8nt de 10 en IO%, et pour des temperetures allant de 900ยฐC jusqu'8 50" en-dessous des points de fusion. Les result8ts sent. correctement d&its par des courbes obeissant 8 une loi d'Arrhenius. SELBSTDIFFIJSION IN KUBISCH-RAUMZENTRIERTEN TITAN-VANADIUM-LEGIERUNGEN Die Di~~io~koeffizienten von **Ti und 18V in Ti~n-Vigil-~gierungen wurden in Abstrinden von 10 Gew.-0h in Temperaturbereich von 900ยฐC bis etwe 50ยฐC in der N&he des Schmelzpunktes bestimmt. Die Daten konnen in befriedigender Weise duroh kontinuierlich gekriimmte Kurven im Arrhenius-Diagramm dargestellt werden.

## Oriented bicrystals of a 3 per cent silicon iron alloy were prepared with a common [011] direction, and were used in a study of intergranular diffusion in the body-centered lattice. The penetration of iron at the grain boundary during diffusion was obtained by an autoradiographic technique. Th
