1. 1. Weight Optimization of Vertical-Axis Wind Turbine Blades constructed in Swedish Fossil Free Steel : With respect to fatigue life time

   Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Författare :Johannes Hall; Albin Larsson; [2023]
   Nyckelord :VAWT; Wind Turbine Blade; SSAB; Fossil-Free; Weight Optimization; Topology Optimization; Sizing Optimization; NACA 0018; STRENX 1300; Abaqus; Tosca Structure; VAWT; Vindturbinblad; SSAB; Fossilfritt; Viktoptimering; Topologioptimering; Size-Optimering; NACA 0018; STRENX 1300; Abaqus; Tosca Structure;

   Sammanfattning : Wind turbines have been utilized for centuries to harness energy from the wind. Commercial wind turbine blades are typically made from composite materials, which are difficult to recycle, leading to blades ending up in landfills at the end of their lifecycle. Additionally, these materials contribute to microplastic pollution. LÄS MER

3. 2. Resistance Element Welding of Ultra High Strength Steel to Aluminium

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Malte Eriksson; [2023]
   Nyckelord :;

   Sammanfattning : The automotive industry strives towards decreased vehicle weight in order to decrease green house gas emissions. To create lighter vehicles, new lighter materials need to be implemented. One issue with new materials is that the traditional joining methods in many cases meet their limitations. LÄS MER

4. 3. Projection Nut Welding to High- and Ultra-high Strength Steels

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Love Englund; [2023]
   Nyckelord :mechanics; solid mechanics; material mechanics; welding; resistance welding; projection welding; nut welding; high strength steel; ultra high strength steel; uhss; coated boron steel; mekanik; hållfasthetslära; materialvetenskap; svetsning; motståndssvetsning; projektionssvetsning; muttersvetsning; belagt borstål;

   Sammanfattning : In an effort to increase the fuel efficiency of cars more widespread use of higher strength steels is seen for their high strength-to-weight ratio. Thesesteels are more limited in their formability and tendency to harden than conventional steels, complicating manufacturing. LÄS MER

5. 4. Friction Element Welding of Ultra High Strength Steels to Aluminium Alloys

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Hilda Vestberg; [2022]
   Nyckelord :friction element welding; UHSS; aluminum; ejoweld; dissimilar welding;

   Sammanfattning : To address the concerns of simultaneously improving crash performance and fuel efficiency in the automotive industry, multi-material car bodies are becoming increasingly popular. Aluminium and steel are two materials whose properties complement each other well for this application. LÄS MER

7. 5. 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
