Phase and Morphological Evaluation of Mechanically Activated Sintered YAG Powders
چکیده انگلیسی

High physical properties of sintered ceramics due to lower sintering temperatures and smaller grain sizes are of a great interest for researchers. In this study, YAG phase was formed successfully with mechanical activation of powder mixtures. The powders were compacted and sintered at 3 different temperatures to evaluate the sintering density, phase formation and grain morphology. It was found that increasing activation time increases the relative density according to unactivated sample sintered at same temperatures. The 80% of theoretical density was reached which indicates the partial liquid phase formation took place. Experiments for further investigations are carried on.
