  1. 1. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Jessica Jacobs; [2021]
    Keywords : ;

    Abstract : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. READ MORE

  2. 2. Simulation of Gradient Formation in Cemented Carbides

    University essay from KTH/Materialvetenskap

    Author : Armin Salmasi; [2016]
    Keywords : Cemented Carbides; Gradient; Simulation;

    Abstract : The aim of the present work is to study the formation of the cubic carbide phase (gamma phase) free gradient zone and the gamma cone structure at the edges of gradient sintered cemented carbides. Four types of cemented carbides; WCTi(C,N)-Co, WC-Ti(C,N)-Ni, WC-Ti(C,N)-Fe, WC-(Ti,Ta,NB)(C,N)-Co were gradient sintered and the thicknesses of the gradients were measured. READ MORE

  3. 3. Investigation of the Cr solubility in the MC phase where M = Ti, Ta

    University essay from Uppsala universitet/Strukturkemi; Uppsala universitet/Oorganisk kemi

    Author : Anna Ehrenborg; [2016]
    Keywords : cubic carbides; Cr solubility;

    Abstract : In this work the chromium solubility in MC, and M in Cr3C2 and Cr7C3 carbides in the Ti-Cr-C and Ta-Cr-C system have been examined experimentally. Special attention is given to the cubic MC phase due to its frequent use in industrial cemented carbides. READ MORE

  4. 4. CALPHAD study of cubic carbide systems with Cr

    University essay from KTH/Materialvetenskap

    Author : Zhangting He; [2015]
    Keywords : CALPHAD; cubic carbide; thermodynamics;

    Abstract : Cubic carbides (titanium, tantalum, niobium, and zirconium carbides) can constitute a significant proportion of so-called cubic and cermet grades, where it is added to substitute a portion of tungsten carbide. It is thus critical to understand and be able to thermodynamically model the cubic carbide systems. READ MORE
