  1. 1. Mechanical and tribological characterization of additive manufactured Co-alloyed tool steels aimed for cutting tool bodies

    Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Jijesh Rajan; [2022]
    Nyckelord :Maraging steels; Selective laser melting; microstructure; wear; Modified 18Ni300; Osprey MAR;

    Sammanfattning : A drill tool body operates under tough cutting conditions where it is subjected to severe rubbing at the drill flute margin by the sliding chips. The tool wear caused by the contact stresses of the high-speed sliding chips is one of the common damage mechanisms observed in drill tool bodies. LÄS MER

  3. 2. Mechanical and tribological characterization of additivemanufactured Co-free tool steels aimed for cutting tool bodies

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Mayur Mane; [2021]
    Nyckelord :Co-free maraging steels; Co-free W360 AMPO alloy; hot-work tool steel; Selective laser melting; microstructure; wear;

    Sammanfattning : Additive manufacturing (AM) is an emerging and interesting technology that enables some of theproduct development projects (PDPs) to produce products that have mechanical and tribologicalproperties comparable to products that are conventionally manufactured. Selective laser melting(SLM) is an additive manufacturing technology that is predominantly used for the production of metalbased components (i. LÄS MER

  4. 3. Linkage of Macro- and Micro-scale Modelling Tools for Additive Manufacturing

    Master-uppsats, KTH/Materialvetenskap

    Författare :Julia Sjöström; [2020]
    Nyckelord :Maraging steel; selective laser melting; temperature evolution; macro-scale modelling; segregation; ICME.;

    Sammanfattning : Additive manufacturing methods for steel are competing against commercial production in an increasing pace. The geometry freedom together with the high strength and toughness due to extreme cooling rates make this method viable to use for high-performance components. The desirable material properties originate from the ultrafine grain structures. LÄS MER

  5. 4. Tribological characterisation of additively manufactured hot forming steels

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Anna Vikhareva; [2020]
    Nyckelord :High temperature tribology; additive manufacturing; hot stamping; maraging steel; H13; galling;

    Sammanfattning : Over the last decade, the application of ultra-high strength steel as safety components and structural reinforcements in automobile applications has increased due to their favourable high-strength-to-weight ratio. The complex shaped components are widely produced using hot stamping. LÄS MER

  7. 5. Surface Finishing and Corrosion Resistance of 3D Printed Maraging Steel

    Master-uppsats,

    Författare :Yinan Shao; [2020]
    Nyckelord :Surface finishing; corrosion resistance; selective laser melting; microstructure; maraging steel;

    Sammanfattning : 3D printing, also known as additive manufacturing (AM), has got rapidly developed since 1987. Compared with conventional manufacturing methods, 3D printing provides some advantages such as increasing material utilization and less waste of material. LÄS MER
