Paper Abstract

The spectral transmittance of mixed silver-halide polycrystalline fibers was measured while they were undergoing repeated bending leading to mechanical fatigue. Microscopic mechanical defects were detected through their influence on the optical losses, without interfering with the deformation. Optical and mechanical lifetimes of the fibers were found to depend on the composition and to be larger for highly mixed compositions. Scanning electron microscope observations of fatigued fibers revealed strong influence of the fiber composition on the fatigue damage. This dependence on the composition was explained using a theoretical model of solid-solution strengthening.
