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 ...

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.

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 ...

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 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.

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 ...
