Phase Formation and Microstructure of Ceramics at Selective Laser Synthesis in Al2o3–Tio2-Y2o3 Powder Compositions

Phase Formation and Microstructure of Ceramics at Selective Laser Synthesis in Al2o3–Tio2-Y2o3... Phase formation processes in the zone of directional laser irradiation of compacted Al2O3–TiO2–Y2O3 mixtures have been investigated. It has been established that phase formation was carried out within the framework of binary systems Al2O3–Y2O3 and Y2O3–TiO2. The texture of the surface of tracks and the microstructure of the obtained crystalline body depend on the ratio of the phases formed during rapid cooling of the melt and temperature distribution of the material in longitudinal and transverse directions in heating. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advances in Ceramic Science and Engineering Science and Engineering Publishing Company

Abstract

Phase formation processes in the zone of directional laser irradiation of compacted Al2O3–TiO2–Y2O3 mixtures have been investigated. It has been established that phase formation was carried out within the framework of binary systems Al2O3–Y2O3 and Y2O3–TiO2. The texture of the surface of tracks and the microstructure of the obtained crystalline body depend on the ratio of the phases formed during rapid cooling of the melt and temperature distribution of the material in longitudinal and transverse directions in heating.
