  1. 1. Modeling of Precipitation by Structural Phase-Field Crystal Method

    Master-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Jacob Holmberg-Kasa; [2021]
    Nyckelord :strain-age cracking; SAC; structural phase-field crystal; XPFC; nickel-based alloys; precipitation;

    Sammanfattning : Nickel-based alloys are used in components such gas turbines within the aerospace industry and electric power generation due to its high tensile, rapture and creep strength. Increasing the efficiency of gas turbines are crucial to reduce emissions within the aerospace industry and increasing power gain for electric power generation. LÄS MER

  3. 2. Economic and technic aspects on post-weld treatment of welded structures exposed to fatigue loads

    Master-uppsats, KTH/Industriell produktion

    Författare :Johan Ankre; [2021]
    Nyckelord :;

    Sammanfattning : It has been known for a long time that we live on a planet with a limited stock of resources. The world population is increasing, more products are being produced and humans are consuming more in a lifetime than the planet can recover. It is a constant competition between industries to keep their prices down and get consumers to buy their product. LÄS MER

  4. 3. Fatigue and Ultimate StrengthAssessment of Post Weld TreatedStrenx 1100 Plus Butt Welds

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Tobias Jonsson; [2020]
    Nyckelord :;

    Sammanfattning : The demand of stronger and lighter constructions are rapidly growing. Today's applications vary over a large range industries where the requirements are di_erent from product to product. Therefore, the focus of much research are the 3rd generation of so called Advance High-Strength Steels (AHSS). LÄS MER

  5. 4. Manufacturing of Welded Rings : Evaluation of Post-Weld Operations

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Jim Andersson; [2019]
    Nyckelord :FBW; flash butt welding; low alloy steel; metallurgy;

    Sammanfattning : Pipe and ring blanks can be produced in several different ways. Today's focus on environmental effects motivates companies to develop processes that are as efficient as possible in their production. Ringsvets AB is a company that produces pipe and ring blanks from a flat stock by rolling and welding the piece to make it stay in its desired form. LÄS MER

  7. 5. Utökade krav för svetsade stålkonstruktioner vid efterbehandling av svetsar

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Erika Olsson; Jenny Abrahamsson; [2019]
    Nyckelord :Fatigue; fatigue strength; weld; Post Weld Treatment; acquis; Utmattning; utmattningshållfasthet; svets; Post Weld Treatment; regelverk;

    Sammanfattning : Stålindustrin står för 7 % av världens koldioxidutsläpp. För att minska industrins miljöpåverkan är ett alternativ att introducera konstruktioner i höghållfasta stål eftersom det ger möjlighet till slankare konstruktioner och därmed mindre materialåtgång. LÄS MER
