  2. 6. Preparation and characterisation of refractory whiskers and selected alumina composites

    Author : Mats Carlsson; Mats Johnsson; Tor Grande; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; VLS-growth; Characterisation; Whiskers; Sintering; Ceramic composites; Inorganic chemistry; Oorganisk kemi;

    Abstract : A whisker is a common name of single crystalline inorganic fibre of small dimensions, typically 0.5-1 μm in diameter and 20-50 μm in length. Whiskers are mainly used as reinforcement of ceramics. This work describes the synthesis and characterisation of new whisker types. READ MORE

  5. 8. Continuous Fibre Reinforced Oxide/Oxide Composites

    Author : Magnus Holmquist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polycrystalline oxide fibre; zirconia; single crystal oxide fibre; hot isostatic pressing; hot pressing; alumina; mullite; sapphire; tape casting; interface; VibroIntrusion; interphase; continuous fibre reinforced ceramic composite; mechanical properties; oxide fibre; ceramic matrix composite;

    Abstract : The appealing properties of ceramics include retention of strength and hardness at high temperatures, chemical inertness and low density. However, monolithic ceramics fail in a brittle, unpredictable manner making them unsuitable for many applications where reliability is a key requirement. READ MORE

  6. 9. Deformation and Fracture of Ceramics and Ceramic Composites

    Author : Thomas Hansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : An understanding of the deformation and fracture behaviour of ceramic materials is of considerable importance in the development of ceramics as reliable structural materials. Of particular interest is how such behaviour is influenced by the microstructure, for example in multiphase materials such as composites. READ MORE

  7. 10. Local structure and composition : in additively manufactured bulk metallic glasses and composites

    Author : Inga Katharina Goetz; Jochen M. Schneider; Björgvin Hjörvarsson; Ulf Jansson; Maria Teresa Pérez Prado; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; additive manufacturing; bulk metallic glasses; nanoscale clustering; convective flow; laser nitriding; laser powder bed fusion; metallic glass - ceramic composites; oxygen impurities; mechanical properties; magnetic properties; viscosity; Fysik; Physics;

    Abstract : Additive manufacturing enables the production of complex multi-material geometries and bulk metallic glass parts beyond their critical casting thickness. The local modification of structure, composition, and properties is explored in this thesis with the aim to design novel composite materials and functional gradients. READ MORE
