Self-diffusion in aluminum at low temperatures
(2014-01-20)
Values of the self-diffusivity of pure aluminum in the temperature range 130∮ to 200° have been determined by measuring the rate of annealing of prismatic and faulted dislocation loops in thin foils of quenched 99.999 pct ...
Cr Self-Diffusion Mundy 1981
(2013-07-03)
Self-diffusion in chromium single crystals has been measured over the temperature range
1073 to 1446 K. These data, when combined with earlier measurements from this laboratory
over the. range 1370—2090 K, yield a plot ...
DIFFUSION OF Ti44 AND V48 IN TITANIUM
(2013-07-03)
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 ...
Al Self-diffusion, Beyeler 1968
(2014-01-19)
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. ...
Ni Self-Diffusion
(2013-06-26)
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 ...
Mg Self-Diffusion
(2013-08-09)
The self-diffusion of magnesium along the c-axis and perpendicular to it has been investigated in the temperature range from 500 to 630 C.
On the Anomalous Self-Diffusion in B.C.C. Titanium
(2013-07-03)
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 ...
Al Impurity Diffusion in Mg
(2013-05-07)
The diffusion of Al in polycrystalline Mg (99.9%) was studied via depth profiling with secondary ion mass spectrometry in the temperature range of 573-673 K, utilizing the thin film method and thin film solution to the ...
Mg Self-Diffusion Pavlinov 1968
(2013-08-29)
It is found that the parameters of self-diffusion and carbon diffusion in calcium are in good agreement with the general regularities for self-diffusion in pure metals and interstitial impurity diffusion in metals with a ...
Study of Si self-diffusion by nuclear techniques
(2014-02-10)
By using ion implantation for preparation and p, γ-reactions for analysis of 30Si profiles the Si self-diffusion has been studied in the temperature range of 830–1200°C. The results reveal unambiguously that the diffusion ...
