13. Projeto e fabricação de moldes para prensagem isostática utilizando tecnologias CAD/CAE e prototipagem rápida. / Design and manufacturing of moulds in isostatic pressing using CAD/CAE technology and rapid prototyping.
This work presents a methodology for the design and fabrication of ceramic powder isostatic pressing moulds using CAD and CAE tools and Rapid Prototyping. The isostatic pressing process was simulated using the finite element method. The compaction behavior of ceramic powder is described by the Drucker-Prager/cap constitutive model and the behavior of elastom

14. Processamento de pós ultrafinos e nanométricos por moagem de alta energia para a obtenção de compósitos cerâmicos Al2O3-(5%vol.)TIC. / Processing of ultra-fine and nanometric powders by high energy milling to produce Al2O3-(5%vol.)SiC and Al2O3-(5%vol.)TiC ceramics composites.
The major objective of this thesis was to study the processing behaviour of Al2O3 ultra-fine and nanosized powders obtained by high energy milling (HEM), to produce, after forming and sintering, Al2O3 .(5%vol.)SiC and Al2O3 .(5%vol.)TiC ceramics composites with high density. This aim arises from the fact that processing difficulties of ultra-fine powders are
