  1. 1. Environmental, Resource and Health Assessments of Hard Materials and Material Substitution: The Cases of Cemented Carbide and Polycrystalline Diamond

    Författare :Anna Furberg; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Life cycle assessment; polycrystalline diamond; disability-adjusted life years; material flow analysis; machining tools; cemented carbide;

    Sammanfattning : The conventional hard material used in manufacturing industry, cemented carbide (WC-Co), mainly consists of the geochemically scarce elements tungsten and cobalt. This use of scarce resources could potentially be avoided by a material substitution to the more abundant and largely carbon-based material polycrystalline diamond (PCD). LÄS MER

  2. 2. Environmental, Resource and Health Impacts of Hard Materials

    Författare :Anna Furberg; Chalmers University of Technology; []
    Nyckelord :MFA; life cycle assessment; material flow analysis; cemented carbide; disability-adjusted life years; LCA; DALY; hard metal; tire stud;

    Sammanfattning : The importance of hard materials for society is illustrated by the fact that entire historical time periods have been named after the predominant hard material used at that time. In the latest century, the introduction of the hard material cemented tungsten carbide with cobalt (WC-Co) has contributed to the economic growth we have seen and this material is crucial for the manufacturing industry of today.
