X-ray line broadening study of splatquenched Ag-Sn alloys

  • A. M. Tonejc

Microstrains, effective particle sizes, and stacking fault probabilities were determined by analysis of X-ray powder pattern peaks of splat-quenched Ag-6 at % Sn, Ag-8.2 at % Sn and Ag-11 at % Sn alloys.

The shapes and positions of all available (h k l) reflections for Cu radiation were recorded, using focusing Bragg-Brentano X-ray geometry. To measure peak positions, Co radiation and a Seeman-Bohlin camera were used with an internal standard.

Fourier analysis and Stokes correction were used. The separation of particle sizes and microstrain components was performed using the Warren-Averbach and the single-profile methods. Errors arising during the separation of particle sizes and microstrains from an inaccurate estimation of background intensity, and the influence of standards with different annealing treatments, were considered.

The particle sizes and microstrains were found to be anisotropic. This anisotropy was due to the presence of stacking faults and an irregular distribution of dislocations in asquenched samples. Peak shift analysis showed that some macrostresses remained after plastic deformation caused by quenching. It appears that better quenching produces thinner samples and higher macrostresses. The particle sizes, microstrains and compound stacking fault probabilities were compared with corresponding values for cold-worked filings and bulk compressed alloys.
