  1. 1. Cemented Carbide Sintering Constitutive Relations and Microstructural Evolution

    University dissertation from Stockholm : Materialvetenskap

    Author : Anders Petersson; KTH.; [2004]
    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

  2. 2. Sintering of cemented carbides : experiments and modeling

    University dissertation from Stockholm : Materialvetenskap

    Author : Sven Haglund; KTH.; [1998]
    Keywords : ;

    Abstract : During sintering of cemented carbides large volumetricshrinkage takes place. About half the volume of the originalgreen body is lost during this process. Due to lotal densitydifferentes within the green body undesired shape changes mayalso occur during sintering. READ MORE

  3. 3. Strength and Stability of Interfaces in Cemented Carbides

    University dissertation from Stockholm : Materialvetenskap

    Abstract : Cemented carbides are hard composite materials of great technological importance. They are widely used as tool materials in a large variety of applications where the demands on hardness and toughness are high, including e.g.≈mining, turning, cutting, and milling. READ MORE

  4. 4. Atomistic modeling of interfaces in WC-Co cemented carbides

    University dissertation from Stockholm : Materialvetenskap

    Author : Martin Petisme; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; analytic bond order potentials; weing; WC-Co; grain boundary sliding; grain boundaries; density functional theory; molecular dynamics; interfaces; cemented carbides;

    Abstract : Grain and phase boundaries are crucial in understanding the properties of real materials. In this thesis, interfaces in WC–Co cemented carbide are modeled atomistically using density functional theory (DFT) and analytic interatomic potentials. READ MORE
