Development of a morphological texture in relation with the crystallographic texture during sintering of strontium hexaferrites

Résumé

Quantitative analysis of grain size, grain shape, morphological and crystallographic texture has been performed in strontium hexaferrites materials, sintered from filter-pressed powders oriented or not with a magnetic field. The results provide evidence for anisotropic and abnormal grain growth at high temperature (T ≥ 1250 °C). A morphological texture develops during heating for oriented samples, with plate-like grains preferentially aligned with their larger facets perpendicular to the direction of field application. A quantitative analysis of the morphological texture in 3D has been performed and the relation between morphological and crystallographic texture is identified from the results. The increase in crystallographic texture is related to grain growth.
