    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cemented carbide; ICME; Materials Design; alternative binder; hardness; AIMD; liquid diffusion; frozen-in solubilities; DICTRA; surface gradients; labyrinth factor; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : The development of alternative binder systems for tungsten carbide (WC) based cemented carbides has again become of relevance due to possible changes in EU regulations regarding the use of Cobalt (Co). A framework for the ICME (Integrated Computational Materials Engineering) based Materials Design is presented to accelerate the development of alternative binder systems. LÄS MER
