  3. 3. Influence of Microstructure on the Machinability of Prehardened Mould Steels

    Författare :Seyyed Mohammad Hamed Hoseiny; Chalmers University of Technology; []
    Nyckelord :Prehardened mould steels; Milling; Drilling; Turning; Tool life; Machinability;

    Sammanfattning : Mould steels are mainly employed in moulding of plastic products, and also some metals withlow melting temperature such as magnesium alloys. The ever-growing usage of plastics in theindustry, especially the automotive industry, and in everyday life, has increased the utilizationof mould steels. LÄS MER

  4. 4. Laser Based Powder Bed Fusion of Plain Carbon and Low-Alloy Steels: Microstructure and Processability

    Författare :William Hearn; Chalmers University of Technology; []
    Nyckelord :Low-Alloy Steel; Additive Manufacturing; Lack of Fusion Porosity; Laser Based Powder Bed Fusion; Plain Carbon Steel; Intrinsic Heat Treatment; Keyhole Porosity; Cold Cracking;

    Sammanfattning : Despite the prominence of laser based powder bed fusion (LB-PBF) as an additive manufacturing technique, the number of alloys that have been approved for the process remains limited. In traditional manufacturing, ferrous alloys are the most common alloy group, consisting primarily of plain carbon and low-alloy steels. LÄS MER
