  3. 22. WC grain size distribution during sintering of WC-Co cemented carbides

    University essay from Lunds universitet/Materialteknik

    Author : Oscar Bjäreborn; [2016]
    Keywords : hardmetal; cemented carbides; WC; EBSD; grain size distribution; microstructure; coercivity; hardness; toughness; sintering; growth inhibition; Technology and Engineering;

    Abstract : The grain growth of WC in WC-7%Co cemented carbides with Cr-addition was investigated for cemented carbides synthesized from four different raw materials varying in grain size. Cr additions were 4%of the Co binder phase. To investigate the effect of Cr on grain growth two of the raw materials were also synthesized without Cr-additions. READ MORE
