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

    Author : Maheswaran Vattur Sundaram; Chalmers tekniska högskola; []
    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

  4. 2. Nanopowder as sintering aid for water-atomized ferrous powder

    Author : Swathi Kiranmayee Manchili; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; master sintering curve; dilatometry; reduction kinetics; thermal analysis; compaction; nanopowder; surface oxide; hydrogen; sintering; water-atomized iron powder; water-atomized steel powder;

    Abstract : Press and sinter powder metallurgy steels are cost-effective solutions for structural applications. There is a constant drive for improvement in the density of these powder metallurgy steels to expand their usage in high-performance applications. READ MORE

  5. 3. Characteristics and Sintering of Fine Water-atomized and Carbonyl Iron Powder

    Author : Johan Wendel; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sintering; powder metallurgy; iron powder; dilatometry; surface analysis; thermal analysis;

    Abstract : Various types of iron powder are extensively used in the powder metallurgy (PM) industry. Water-atomized iron powder is commonly used as the base in many low-alloyed steel products manufactured through the conventional 'press and sinter' route, while carbonyl iron powder is often used for metal injection moulded (MIM) components.

  6. 4. Processing Methods for Reaching Full Density Powder Metallurgical Materials

    Author : Maheswaran Vattur Sundaram; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas atomised powder; water atomised powder; high density powder metallurgical materials; high density; master alloys; liquid phase sintering; sintering; high velocity compaction; hot isostatic pressing; additive manufacturing;

    Abstract : Powder metallurgy (PM) is one of the most cost effective methods for manufacturing structural components with complex shapes. Utilisation of the metal powder to shape the components allows to minimise material waste and increase energy efficiency. READ MORE

  7. 5. Cemented Carbide Sintering : Constitutive Relations and Microstructural Evolution

    Author : Anders Petersson; KTH; []
    Keywords : Cemented carbides; Sintering; Constitutive relations; Microstructure; Densification; Modelling;

    Abstract : 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. READ MORE
