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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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.

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 ...

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 ...
