Abstract

The Debye characteristic temperature, θ, of carbonyl iron has been determined as being between 433 and 445°K at an ambient temperature of 310°K from an X-ray diffraction study utilizing both monochromatlzed and filtered radiation by both stationary and scanning slit methods.

In computing θ, several factors have been taken into consideration; the diffracted integrated intensities have been corrected for temperature diffuse scattering (TDS); the temperature gradient through the specimen was found to be critical and given as 160°K/in. at 95°K; corrections for the temperature dependence of θ have been made; and extinction effects were investigated, and results contrary to those of U'lna, Krltskaya, and Kurdyumov have been found.

The TDS corrected values for static and dynamic atomic displacements are also given.
