    Abstract : As Ti-alloys become more and more utilized the need for efficient and robust manufacturing of Ti-alloy components increase in importance. Ti-alloys are more difficult to machine than e.g. steel, mainly due to their poor thermal conductivity leading to rapid tool wear. READ MORE

  5. 8. Atomic-scale modelling of interfaces in cemented carbides: wetting and strength

    Author : Martin Gren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; adhesion; density functional theory; hardmetals; cemented carbides; WC-Co; surfaces; interfaces; grain boundaries; wetting; phase boundaries;

    Abstract : Cemented carbides are composite materials of great technological and industrial importance. They have a unique combination of hardness and toughness and are therefore used widely as tool materials in applications where both high hardness and toughness are demanded. These applications include among others: mining, turning, cutting and milling. READ MORE
