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 ...
Al Self-Diffusion Fradin, Rowland 1967
(2013-10-01)
Using a radio‐frequency field pulse technique which enables measurement of slow atomic diffusion by means of nuclear magnetic resonance we have obtained, for nominally 6–9's pure Al, an activation energy for self‐diffusion ...
Cr Self-Diffusion Paxton Gondolf 1959
(2013-07-08)
Measurement of the radioactivity of the surface reduced by partial diffusion of the radioactive chromium as well a measurement of the radioactivity after gradual working off of thin surface films, after coating radioactive ...
Cr Self-Diffusion Mundy 1976
(2013-07-03)
The diffusion of "Cr in chromium has been measured between 1100 and 1820'C, and the data fit the
Arrhenius relation D = 970exp(—104000/R T) cm'sec '. Isotope-effect measurements, using isotopes "Cr and
"Cr, have been ...
Mg Self-Diffusion
(2013-08-09)
The determination of the self-diffusion coefficient of magnesium has been made possible recently by discovery of a radioactive isotope, Mg-28 having a half-life of 21.3 hr, and subject to manufacture in useful quantity.
Al-Co, Co-Fe Diffusion Mobilities, Ni/Rene88, IN718/Rene88
(2013-05-05)
A multicomponent diffusion mobility database for the Ni-rich fcc phase [2002Cam] is evaluated by comparing diffusion simulations to two experimental multicomponent Ni-base superalloy diffusion couples: Ni/Rene´-88 and ...
Cr Self-Diffusion Askill and Tomlin 1965
(2013-07-08)
Self-diffusion measurements have been made in the temperature range 1000 degrees c to 1550 degrees c in order to resolve some uncertainties arising from previously published data from several separate investigations covering ...
