1. Thermodynamic and kinetic investigation of systems related to lightweight steels
Sammanfattning : Lightweight steels have attracted considerable interest for automobile applications due to the weight reduction without loss of high strength and with retained excellent plasticity. In austenitic Fe-Mn-Al-C steels, the nano-precipitation of the κ-carbide within the austenitic matrix significantly contributes to the increase in yield strength. LÄS MER
2. Fatigue and Fracture of High-Strength Steels : Improving Reliability in Strength Assessment
Sammanfattning : Structural steel plays a fundamental role in the heavy industry, serving as a key material for numerous load-bearing products and equipment. Its widespread use is attributed to its robustness, resistance to wear, ease of use in construction, and cost-effectiveness. LÄS MER
3. Dissimilar joining of aluminium to ultra-high strength steels by friction stir welding
Sammanfattning : Multi-material structures are increasingly used in vehicle bodies to reduce weight of cars. The use of these lightweight structures is driven by requirements to improve fuel economy and reduce CO2 emissions. The automotive industry has replaced conventional steel components by lighter metals such as aluminium alloy. LÄS MER
4. A Study on Sandwich Structures : Development, Mechanical Characterization and Numerical Modeling
Sammanfattning : Legislative demands force the automotive industry to reduce greenhouse gas (GHG) emissions. At the same time, crashworthiness must not be compromised. A ve-hicle’s GHG emissions, such as carbon dioxide, is dependent on its fuel consump-tion. Lowering the vehicle weight, reducing fuel consumption, will therefor reduce emissions. LÄS MER
5. Towards Geometry Assurance of Laser Processed Sheet Metal Components
Sammanfattning : Stricter emission norms have propelled the automotive industry towards lightweight transportation solutions to reduce the environmental impact. The industry has adapted to cost effective lightweight sheet metal solutions to control the vehicle weight as well as maintain the safety standards of the vehicle. LÄS MER
