  1. 6. Novel approaches for achieving full density powder metallurgy steels

    Författare :Maheswaran Vattur Sundaram; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cr- and Mo-alloyed PM steels; vacuum sintering; high density; full density; hot isostatic pressing.; cold isostatic pressing; liquid phase sintering; master alloy; double pressing-double sintering; powder metallurgy steels; sintering; water atomised powder;

    Sammanfattning : Powder metallurgy (PM) is one of the most resource-efficient methods for manufacturing structural components with complex shapes. The utilisation of the metal powder to shape the components allows to minimise material waste and increase energy efficiency. LÄS MER

  3. 7. Net-Shape Consolidation of Water-Atomised and Gas-Atomised Steel Powder Towards Full Density

    Författare :Anok Babu Nagaram; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hot isostatic pressing; high temperature sintering; sintering atmosphere; cold isostatic pressing; Powder metallurgy; Prealloyed with Cr PM steel; high density; PM steel;

    Sammanfattning : Powder metallurgy (PM) provides resource- and cost-efficient routes to create near-net shape products compared to conventional metal fabrication techniques. To improve the mechanical performance of PM steels, it is a prerequisite to enhance the density of the material. LÄS MER

  4. 8. Hot isostatic pressing of ceramics and influence of glass encapsulation

    Författare :Anna-Karin Westman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Konstruktionsmaterial; Engineering Materials;

    Sammanfattning : Hot isostatic pressing (HIP) is one of the industrial techniques for production of structural ceramics. A high quality of the as-HIPed surface is highly desirable, as it may make it possible to minimise or eliminate costly finishing machining. LÄS MER

  5. 9. Modelling and simulation of hot isostatic pressing of metal powder

    Författare :Ales Svoboda; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : .... LÄS MER

  7. 10. The isostatic pressure processing of high Tc superconductors and their properties

    Författare :John Niska; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Sammanfattning : The high Tc superconductors are highly anisotropic, ceramic materials which makes it difficult to sinter them at atmospheric pressure to full density. High porosity is detrimental to their mechanical and electrical properties, so the use of isostatic pressures was used to give higher density materials with improved properties. LÄS MER
