  1. 1. Influence of Microstructure in Machining of Nickel and Nickel-Iron Based Alloys

    Författare :Stefan Olovsjö; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear mechanisms; Simulation; Tool wear; Burr; Meta-modelling; Inconel 718; Metal cutting; Superalloy; Waspaloy; Chip morphology; Notch wear; Alloy 718; JMatPro;

    Sammanfattning : Superalloys are used in applications such as turbines, steam power plants and nuclear power systems in components that require good high temperature properties and/or corrosion resistance. They are classified as difficult-to-cut materials and hence, from a sustainable production point of view, tool wear and tool life are major factors when machining these alloys. LÄS MER

  3. 2. On the Effect of Grain Size and Hardness on the Machinability of Superalloys and Chip Deformation

    Författare :Stefan Olovsjö; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Superalloys; Microstructure; Burr; Machinability; Waspaloy; Chip microstructure; Tool wear; Alloy 718;

    Sammanfattning : Superalloys are used in applications such as gas turbines, steam power plants and nuclear power systems that require good high temperature properties and/or exceptional corrosion resistance. Superalloys are classified as materials that are “difficult to machine”. In production machining is a most commonly occurring procedure. LÄS MER
