  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

  5. 4. Fracture prediction of stretched shear cut edges in sheets made of Dual-Phase steel

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Johannes Falk; [2017]
    Nyckelord :Strain; DP steel; Dual-phase steel; Autoform; Aramis; Fracture strain; Advanced High Strength Steels; AHSS; Fracture prediction;

    Sammanfattning : Dual-Phase (DP) steels, part of the group of Advanced High Strength Steels (AHSS), are used by car manufactures due to its large strength to weight ratio. The high strength of the DP steel does have a negative impact on the formability during sheet metal forming and stretch forming, e.g. LÄS MER

  7. 5. Super Duplex Stainless Steel Surfaces and their Effects on Marine Biofouling

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Adrian Falk; [2017]
    Nyckelord :Marin tillväxt; superduplex; bottenfärg; havstulpaner;

    Sammanfattning : Some of the world’s most ancient, but still viable, organisms have since the beginning of maritime caused problems for the industry. The problems affect both the longlivety and efficiency of ships which is caused by the mere presence of organisms attached to the ship hulls. LÄS MER
