Results of fourier analysis and line breadth measurements on molybdenum filings

Abstract

X-ray photographic technique with nickel filtered and crystal monochromated CuK_α radiation has been used to record (110), (220), (200) and (400) reflections from molybdenum filings. Stokes' method has been used to apply a correction for instrumental broadening. The line profiles have been analysed with different methods. The ratio of domain sizes in two directionsL(110) : L(100), is approximately 0•97. The slight anisotropy in particle sizes and lattice strains exists even in the annealed state. While no evidence of faulting could be found, the composite broadening is attributed to particle size and lattice strains. The integrated intensities of line profiles obtained from cold-worked and annealed samples are found to be the same within the limits of experimental accuracy.
