Self diffusion of Cr-51 in pure chromium, Cr +20 wt% Ni, Cr +44wt% Ni, and Cr +65%wt Ni has been measured over the temperature ranges of 1000 to 1900, 1000 to 1525, and 900 to 1350 degrees C, respectively.

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 ...

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 ...

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 ...
