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

    Author : Maheswaran Vattur Sundaram; []
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Biomaterial Components Prepared by Titanium Powder Technology

    Author : Mikael Eriksson; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dental; coping; biomaterial; titanium-hydroxyapatite composite; crown; cold isostatic pressing; deformation; titanium powder; high velocity compaction; powder metallurgy;

    Abstract : The main objectives of this work were twofold: First, to determine if a pressed-powder method could be used to fabricate titanium dental copings, and to line out what problems or benefits this new method would have. Second, to test if high velocity compaction of titanium powder could be used to form biomaterial components such as copings or dental implants. READ MORE

  3. 3. Modelling and simulation of powder pressing with consideration of friction

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Bengt Wikman; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : Finite element modelling and simulation of the powder pressing process can be used in the rational development of powder metallurgy (PM) components. Many of the nonlinear finite element (FE) codes available today can be used for powder pressing simulations. READ MORE

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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : John Niska; [1993]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

    Abstract : 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. READ MORE

  5. 5. Synthesis of ytterbium-doped yttrium oxide nanoparticles and transparent ceramics

    University dissertation from Luleå tekniska universitet

    Author : Johanne Mouzon; Luleå tekniska universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

    Abstract : In this thesis, the author reports on a ceramic process leading to transparent ytterbium doped yttrium oxide ceramics. The full production route was investigated, namely: powder preparation, compaction and sintering. First, yttria nano-powder was fabricated from a precursor with transient morphology, i.e. READ MORE
