ANALYSIS OF THE BROADENING OF POWER PATTERN PEAKS FROM COLD WORKED FCC AND BCC METALS,

Abstract

Using CuK alpha radiation, the peak profiles of the cold worked and annealed filings of W, Nb, Al and Ag-In alloys were recorded with a standard focusing diffractometer. The Rachinger method was applied to separate the K alpha sub 1 and K slpha sub 2 peaks, and the K alpha sub 1 peaks were subjected to a Fourier analysis. Elimina tion of the instrumental broadening was carried out by the Stokes method which does not require any assumptions concerning the mathematical description of the diffraction peak profile. The Fourier coefficients were separated into the fractions produced by particle size and by strains by thwWarren-Averbach method. (Author)
