  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. Material Transfer Mechanisms during Interaction of Aluminium Alloy and Tool Steel at Elevated Temperatures

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

    Författare :Gabriel Macêdo; [2020]
    Nyckelord :material transfer mechanisms; high temperature tribology; hot metal forming tribology; hot-stamping of aluminium alloys; aluminium alloys;

    Sammanfattning : Hot stamping of aluminium alloys allows for increased formability, decreased springback and the possibility of integrating age-hardening heat treatments into the process. However, it can be challenging due to the occurrence of material transfer of aluminium onto the tool, as aluminium is prone to adhesion even at low temperatures. LÄS MER

  4. 3. Optimization of annealing parameters for SANDVIK 13C26 and 20C strip steels : By MODDE analysis and modified JMAK method

    Master-uppsats, KTH/Materialvetenskap

    Författare :Ahamed Ameen; [2019]
    Nyckelord :Recrystallization; EBSD; Optimization; MODDE; JMAK analysis; strip steels;

    Sammanfattning : The process optimization of continuous annealing furnace, RHF 125, for recrystallization annealing of two steel grades, Sandvik 13C26 and Sandvik 20C has been carried out. To recreate the continuous annealing process carried out in the roller hearth furnace in the industry, samples with different cold reduction rates were chosen from ongoing production lines. LÄS MER

  7. 5. Processens påverkan på rakhet hos bandstål : Från inkommande råmaterial till färdigt halvfabrikat

    M1-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgi

    Författare :Susanna Hämquist; [2018]
    Nyckelord :strip steel; cold rolling; camber; straightness; slitter scorer; bandstål; kallvalsning; kortkrok; rakhet; rullsax;

    Sammanfattning : Examensarbetet har utförts under våren 2017 vid Bergsskolan i Filipstad, i samarbete med voestalpine Precision Strip i Munkfors. Att producera så kostnadseffektivt som möjligt likväl att minimera material som kasseras är något företag idag ser som självklart. På samma gång som detta efterlevs bör även kundnöjdheten maximeras.
