摘要：

The phase formation process in the zone of laser irradiation of Al2O3-TiO2 compacts with different contents of components has been investigated with XRD, electron microscopy, and atomic force microscopy methods. The distinctive feature of laser synthesis is the simultaneous formation of a-and beta-Al2TiO5, which is caused by the non-uniform heating of the material in the irradiation zone. The motion of the eutectic melt under the action of hydrodynamic forces is the motive force for texturing of precipitating crystalline phases during fast cooling. The degree of texturing of Al2O3 and Al2TiO5 crystallites depends on the amount of the formed eutectic melt.
