3664.     ---------------.  [WERT, C. A.]  Measurements on the Diffusion of Interstitial Atoms in Body-Centered Cubic Lattices.  Jour. Appl. Phys., vol. 21, 1950, pp. 1196-1197; Chem. Abs., vol. 45, 1951, p. 1835.

        Rate of diffusion of C in Ta and Nb and of N in a-Fe was measured by effects on internal friction and an elastic aftereffect.  Data covering a range of 104 in rate are reported.
