    Sammanfattning : Replacement of cobalt in cemented carbides has gained in attention recently because threats of regulations due to health issues (cancerogenic effect), increased demand from the electric vehicle industry and the questionable extraction from countries like Democratic Republic of Congo. In this report the use of Ni-based binder as an alternative binder for cemented carbides has been explored. LÄS MER

  3. 2. Effect of carbon activity on microstructure evolution in WC-Ni cemented carbides

    Master-uppsats, KTH/Materialvetenskap
