  1. 1. The Effect of Temperature Gradients During Intercritical Annealing of Advanced High Strength Steels : Method Development for Experimental Streamlining

    Master-uppsats, KTH/Materialvetenskap

    Författare :Helena Ek Jendrny; [2023]
    Nyckelord :AHSS; Gleeble; Intercritical annealing; Retained austenite; Medium Mn Steel; AHSS; Gleeble; interkritisk glödgning; austenit; Medium Mn stål;

    Sammanfattning : The third-generation advanced high strength steels, AHSS, represent an opportunity for today’s steel development, where lighter materials with maintained strength and toughness are in demand. The unique properties of these materials often stem from a tailored microstructure. LÄS MER

    Sammanfattning : The Latin American steel making company Ternium S.A. aims to develop and produce a new type of advanced high strength steel (AHSS) in which the main alloying elements are carbon, aluminium, manganese, and silicon. LÄS MER

  4. 3. Designing a Heat Treatment to Achieve Ductile Advanced High Strength Steels

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

    Författare :Abdellatif Laarich; [2020]
    Nyckelord :Heat treatment; Quenching and Partitioning; Austempering; Quenching and Tempering; High Aluminum Steel; Strenx 700MC; Ductility; Strength;

    Sammanfattning : Heat treatment is a way to significantly change materials properties. When presented with materials that lack certain mechanical properties, it is possible to change its chemical properties and microstructures by applying heat. This can help achieve better yield strength, ductility and toughness. LÄS MER
