  1. 1. Surface integrity on post processed alloy 718 after nonconventional machining

    Författare :Jonas Holmberg; Tomas Beno; Anders Wretland; Johan Berglund; Mikael Olsson; RISE; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Non-conventional machining; post processing; surface integrity; Microstructure; Residual stress; Electron back scattering diffraction; Material removal rate; Manufacturing; Surface and Joining Technology; Bearbetnings-; yt- och fogningsteknik; Production Technology; Manufacturing and materials engineering;

    Sammanfattning : There is a strong industrial driving force to find alternative production technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies allows taking a giant leap to increase the material removal rate and thereby drastically increase the productivity. LÄS MER

  3. 3. Electrochemical machining: towards 3D simulation and application on SS316

    Författare :A. A. Gomez-Gallegos; UK University of Edinburgh; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochemical machining; 3D Simulation; FEM; stainless Steel 316; surface Finish; Maskinteknik; Mechanical Engineering;

    Sammanfattning : Electrochemical machining (ECM) is a non-conventional manufacturing process, which uses electrochemical dissolution to shape any conductive metal regardless of its mechanical properties and without leaving behind residual stresses or tool wear. Therefore, ECM can be an alternative for machining difficult-to-cut materials, complex geometries, and materials with improved characteristics, such as strength, heat-resistance or corrosion-resistance.

  4. 4. Microstructure Modelling of Additive Manufacturing of Alloy 718

    Författare :Chamara Kumara; Per Nylén; Johan Moverare; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-Field Modelling; Laser metal powder directed energy deposition; Electron Beam Melting; Heat Treatment; Superalloy; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : In recent years, additive manufacturing (AM) of Alloy 718 has received increasing interest in the field of manufacturing engineering owing to its attractive features compared to those of conventional manufacturing methods. The ability to produce complicated geometries, low cost of retooling, and control of the microstructure are some of the advantages of the AM process over traditional manufacturing methods. LÄS MER
