An X-ray diffraction study on the microstructure of AgCdZn (α phase) alloys

Abstract

The X-ray diffraction profiles of six ternary alloys of AgCdZn in the cubic α phase have been recorded using a Philips diffractometer. Peak shift, peak asymmetry and Fourier line shape analysis of the profiles are made in order to evaluate the microstructural parameters. It is observed that the stacking fault probability increases with combined solute concentration ( Cd + Zn). The root mean square microstrain 〈ϵ 2〉 1 2 and effective particle size D e along [111] and [100] are found to be anisotropic. The particle size due to faulting D SF , the dislocation density ρ and the parameter γ/μ (γ, stacking fault energy; μ, shear modulus) of these alloys are also evaluated.
