X‐Ray Measurements of Faulting in Ag–Pd Alloys

摘要: A detailed study of x‐ray line broadening has been made in severely cold‐worked filings pure Pd and five Ag–Pd alloys containing 20, 40, 60, 75, 80 wt.% Pd. Debye‐Scherrer shapes recorded a proportional counter diffractometer have analyzed both by Fourier integral breadth methods for the evaluation effective particle sizes (De)hkl rms strains (〈e2〉hkl1/2). It found that 〈e2〉hkl1/2 are anisotropic vary little with composition. The importance faulting particle‐size could also be clearly observed. intrinsic fault densities (α) estimated from peak shifts, although small, show marked variation solute content. Following Otte's analysis, energies (γ) deduced using measured α, 〈e2〉hkl1/2, available shear modulus values. γ values thus arrived at compared those obtained these Harris et al. texture method. was concluded interaction d electrons ...
