  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. Resistance Spot Welding of AlSi-coated Ultra High Strength Steel : An experimental study

    Master-uppsats, KTH/Materialvetenskap

    Författare :Kristofer Hjelmtorp; [2019]
    Nyckelord :RSW; resistance spot welding; usibor; boron steel;

    Sammanfattning : The automotive industry of today faces ever harder requirements from regulatory bodies to increase the fuel efficiency, reduce the carbon footprint and increase the safety of their vehicles. The problem is being tackled in different ways; one of them being the use of innovative materials to reduce the overall weight while improving the crash safety of the vehicle. LÄS MER

  4. 3. Abrasive wear of hard faced ground engaging tool

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :David Eugenio Cantú Gómez; [2017]
    Nyckelord :Ground engaging tool; laser cladding; plough; wear resistance; Jordbearbetning; laserpåsvetsning; nötningsbeständig; plog;

    Sammanfattning : Ground engaging tools are very important components of machinery for agricultural applications, such as soil tillage. Ploughshare points serve as the first point of contact between ploughs and the hard minerals in the soil. LÄS MER

  5. 4. Investigation of thermal spring back of a hot formed 22MnB5 A-pillar with tailored properties

    Uppsats för yrkesexamina på grundnivå, Högskolan Väst/Avdelningen för maskinteknik och naturvetenskap

    Författare :Mattias Lugnberg; Tobias Netz; [2016]
    Nyckelord :Thermal spring back; hot stamping;

    Sammanfattning : In a world where fuel economy and crash safety is becoming an important factor in the automotive industry, the need for materials with very high strength-to-weight ratio is growing rapidly. One of the materials used for this purpose is the boron steel 22MnB5. LÄS MER

  7. 5. Furnace Brazing of AlSi-coated and Uncoated 22MnB5 Steel at Austenite Temperatures

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Adam Häggqvist; [2015]
    Nyckelord :;

    Sammanfattning : By continued advances in mechanical strength of press hardened boron alloyed steel (22MnB5) weight savings can be achieved by the use of less material. However, with reduced material thickness stiffness problems such as buckling arises and the high strength of the material can’t fully be taken advantage of. LÄS MER
