Annealing Kinetics of Voids and the Self-Diffusion Coefficient in Aluminum
The annealing kinetics of voids in 99.9999 wt% pure aluminum were studied over the temperature range 85 to 209 °C in thin specimens by transmission electron microscopy. The isothermal shrinkage of individual voids was ...
Interrelationship between the Diffusion Behaviour and the phase Transformation Characteristics
It has been observed that the metals which exhibit anomalous diffusion behaviour are all allotropic in nature. A hypothesis to rationalise this interrationship between the diffusion behaviour and the phase transformation ...
Self-Diffusion and fast cobalt impurity diffusion in the bulk and in grain boundaries of hexagonal titanium
Bulk Self-Diffusion was measure in alpha-Titanium single crystals between 776 and 1132 K using the radiotracer Ti44 and ion beam sputtering for profile sectioning.
Al Self-diffusion, Messer et al. 1974
Al Self-diffusion, Beyeler 1968
Self-diffusion of gold, copper and aluminium has been investigated for single crystals treated under pressures of 0 to 10 kbars in a temperature range of 700 °C to 990 °C for copper and gold and 400-610 °C for aluminium. ...
DIFFUSION OF Ti44 AND V48 IN TITANIUM
The diffusion of Ti44 and V48 in the b.c.c. phase of iodide titanium has been studied over the temperature range 909-1550°C. The resulting Arrhenius-type plots show curvature with the apparent activation energies and ...
Self-diffusion in nickel single crystals is measured between 813 and 1193 K using ion-beam sputtering as a microsectioning technique. Gaussian activity-depth profiles are observed over about three orders of magnitude in ...
On the Anomalous Self-Diffusion in B.C.C. Titanium
Self-diffusion of the Ti44 is measured in Beta-Titanium under UHV conditions int eh whole range of existence of the bcc phase. The Arrhenius plot shows a strong upward curvature in agreement with previous investigations ...
