1. Projection Nut Welding to High- and Ultra-high Strength Steels
Master-uppsats, KTH/HållfasthetsläraSammanfattning : 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
2. Resistance Spot Welding of AlSi-coated Ultra High Strength Steel : An experimental study
Master-uppsats, KTH/MaterialvetenskapSammanfattning : 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
3. Furnace Brazing of AlSi-coated and Uncoated 22MnB5 Steel at Austenite Temperatures
Master-uppsats, KTH/LättkonstruktionerSammanfattning : 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
4. Termodynamisk utvärdering av borstål
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskapSammanfattning : Vid framställning av olika material är introduceringen av legeringselement ett betydelsefullt område. Vid framställning av stål kan egenskaperna för stålet optimeras genom att styra de kemiska reaktionerna som sker i samband med att stålet legeras. För legeringar av stål är låga halter av grundämnet bor av intresse. LÄS MER
