  1. 11. Spark plasma sintering and deformation behaviour of Titanium and Titanium/TiB2Spark plasma sintering and deformation behaviour of Titanium and Titanium/TiB2 composites

    Författare :Mirva Eriksson; Zhijian Shen; Guocai Chai; Stockholms universitet; []
    Nyckelord :materialvetenskap; Materials Science;

    Sammanfattning : Titanium has been used as a model substance to study how it behaves in a SPS apparatus when heating rate and/or pressure were varied during the sintering and deformation process. The sintering and deformation of Ti in SPS were compared with that occurring in the conventional hot pressing (HP) in order to reveal if there are any positive effects added by the use of SPS.

  3. 12. Novel uses of bio-polymers in composites : from chemistry to processing of materials and food

    Författare :Faraz Muneer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Plant bio-polymers obtained as industrial side-streams (wheat gluten and potato proteins) and specifically designed potato starch and hemp fibres were used to produce composite materials. Fractionated pea protein and pea dietary fibres were used to make pasta-like sheets for production of healthy food. LÄS MER

  4. 13. Carbon Nanotube Polymer Composites: Mechanical, Electrical and Photorefractive Properties

    Författare :Liliana Licea Jimenez; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes; electrical properties; photorefractive properties.; polymer matrix nanocomposites; mechanical properties;

    Sammanfattning : Incorporation of carbon nanotubes (CNT) into polymers is attractive due to the generally good processability of polymers and unprecedented properties of nanotubes. In this work, preparation and matrix known earlier but not employed so-far for nanocomposites are studied towards enhanced mechanical and electrical performances. LÄS MER

  5. 14. Synthesis and Characterization of MgA1ON-BN refractories

    Författare :Zuotai Zhang; Seshadri Seetharaman; Kazuhiro Nagata; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MgAlON-BN composites; Mechanical properties; Thermal shock durability; Thermal diffusivity conductivity; Corrosion resistance.; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : In order to meet the need of metallurgical industry in the world, a new MgAlON-BN composite which can be used for example in special refractory nozzles, tubes and break rings for the continuous casting of steel was studied in the present thesis. The aim was to understand the mechanism of synthesis and their physicochemical properties during the application. LÄS MER

  7. 15. Preparation and characterisation of refractory whiskers and selected alumina composites

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

    Sammanfattning : 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. LÄS MER
