Abstract
The microstructure and hyperfine parameters of Fe3Si powder particles milled in a ball mill are investigated. A model of islands of original structure separated by veins of damaged structure (interfaces) is applied. The contents of both phases derived from Mossbauer spectra are changed by heal treatment. Variations of hyperfine parameters with phase composition are explained as the effect of fluctuations of the magnetization. The isomer shift shows a compression of iron atoms in the interfaces and lattice expansion in the islands of original structure. The enhancement of the hyperfine field in interfaces is explained by the appearance of large “surface-like” magnetic moments.
