Uticaj mikrostrukture na mehaničke osobine kompozitne keramike Al2O3-Y3Al5O12
Effect of microstructure on mechanical properties of Al2O3-Y3AL5O12 composite ceramics
Abstract
U okviru ove doktorske disertacije proučene su dve metode dobijanja
Al2O3-Y3Al5O12 kompozita i ispitan je uticaj mikrostrukture na osobine dobijene
kompozitne keramike. Ispitivanja su obuhvatila metode sinteze Itrijum (Yttrium)
Aluminijum Garneta (YAG) hemijske formule Y3Al5O12 kao i njegove inkorporacije u
alumina (Al2O3) matricu u cilju dobijanja kako poroznog tako i gustog kompozita sa
poboljšanim osobinama u odnosu na čistu aluminu...
Within this doctoral dissertation, two methods of obtaining Al2O3-Y3Al5O12
composite were studied as well as the effects of the microstructure on the properties of
the obtained composite ceramics. The study included the methods of synthesis of
Yttrium Aluminium Garnet (YAG) with chemical formula Y3Al5O12 as well as its
incorporation into alumina (Al2O3) matrix in order to obtain both porous and dense
composites with improved properties relatively to pure alumina...
