    Sammanfattning : In the last decades, significant improvements regarding the design, materials and technology of rock drills have been made. Likewise, in sheet metal forming, forming tools experience very high contact pressures when processing high strength steel sheets. LÄS MER

  3. 2. Wear of high strength steels and ductile iron and its effect on fatigue performance

    Författare :Abdulbaset Mussa; Pavel Krakhmalev; Jens Bergström; Bojan Podgornic; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sliding wear; severe plastic deformation; delamination; WEL and synergy of wear and fatigue; Materialteknik; Materials Engineering;

    Sammanfattning : Machinery components used in demanding applications are required to transmit or carry mechanical loads under severe loading conditions. They are subjected to cyclic loading and repeated sliding contact that in many cases result in a premature failure of components. LÄS MER
