  1. 1. 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

  3. 2. Reliable Carburization of AISI H13 Steel : The Impact of Preoxidation

    Master-uppsats, KTH/Materialvetenskap

    Författare :Martin Palm; [2020]
    Nyckelord :Preoxidation; Case hardening; Uddeholm Orvar® Superior; Passive oxide layers; Iron oxides; Carbon adsorption;

    Sammanfattning : Case hardened Uddeholm Orvar® Superior (Orvar) has the potential to replace currently used materials in shafts inside transmissions, which would lower the overall weight and thus result in lower fuel consumption while maintaining the necessary mechanical properties. However, previous studies have failed to reliably carburize the steel during the case hardening process. LÄS MER

  4. 3. Process development for H13 tool steel powder in binder jet process

    M1-uppsats, Högskolan i Gävle/Maskinteknik

    Författare :George Persson; [2020]
    Nyckelord :Additive manufacturing; H13; toolsteel; binder jetting; processutveckling.;

    Sammanfattning : Additive manufacturing brings versatility and new degree of freedom for part design and manufacturing possibilities. Binder jetting is powder bed printing technique that does not require direct energy transfer rather binding powder metal particles through mechanical entanglement by use of the organic binder.

  5. 4. Independent Project in Chemical Engineering and Materials Engineering : A literature study of powder-based additive manufacturing

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Daniel Feldt; Petra Hedberg; Asker Jarlöv; Elsa Persson; Mikael Svensson; Filippa Vennberg; Therese You; [2018]
    Nyckelord :Additive manufacturing; selective laser melting; electron beam melting; binder jetting; stainless steel; tool steel; nickel alloys;

    Sammanfattning : The focus of this literary study was additive manufacturing (AM) and the purpose was to find general trends for selected materials that have been additively manufactured and compare them to results from other reviews. The raw materials studied were stainless steels 316L, 17-4 PH, 15-5 PH and 420, as well as tool steel H13 and nickel alloys 625, 718 and Hastelloy X. LÄS MER
