  1. 6. 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

  3. 7. 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
