  3. 2. Surface Densification of Solid Wood : Paving the Way Towards Industrial Implementation

    Författare :Benedikt Neyses; Dick Sandberg; Alexander Pfriem; Luleå tekniska universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Science and Engineering;

    Sammanfattning : Surface densification of a piece of solid wood results in an increase in density and in hardness in the whole or a part of the densified material, and is one of the ways of improving the properties and value of low-density wood species. Despite efforts for many years, mass commercialisation of either bulk- or surface-densified wood products has not yet been achieved. LÄS MER

  4. 3. Cemented Carbide Sintering : Constitutive Relations and Microstructural Evolution

    Författare :Anders Petersson; KTH; []
    Nyckelord :Cemented carbides; Sintering; Constitutive relations; Microstructure; Densification; Modelling;

    Sammanfattning : Cemented carbides based on tungsten carbide and cobalt arecommonly produced by a powder metallurgy route including liquidphase sintering. The pressed compact densifies to almost halfits volume during sintering due to pore elimination. LÄS MER

  5. 4. Vertical Extension of Buildings

    Författare :Rikard Nilsson; Avdelningen för Byggproduktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability; Densification; energy-efficient renovation; Urban Development; Stakeholder;

    Sammanfattning : Many policy targets have been developed with the aim of reaching a more sustainable development; more specifically, thestudied policies target energy use and urban growth. For example, by 2050 the aim is that the European Union will havereduced its greenhouse emissions by 90%. LÄS MER

  7. 5. Rapid sintering of ceramics by intense thermal radiation

    Författare :Duan Li; Zhijian Shen; Lutz-Michael Berger; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sintering; sintering by intense thermal radiation; spark plasma sintering; heat transfer; mass transfer; scattering; coalescence; densification; grain growth; numerical simulation; porous ceramic; foaming; nanostructure; hierarchical heterogeneities; permeability; Materials Chemistry; materialkemi;

    Sammanfattning : Sintering is an important processing step for obtaining the necessary mechanical stability and rigidity of ceramic bulk materials. Both mass and heat transfer are essential in the sintering process. The importance of radiation heat transfer is significantly enhanced at high temperatures according to the well-known Stefan-Boltzmann’s law. LÄS MER
