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. Metallurgical investigation in weldability of Aluminium Silicon coated boron steel with different coating thickness.
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Hot-pressed aluminium and silicon coated boron steel is used in the car industry where high tensile strength is of great importance, such as in the safety cage of a car where deformation has to be kept to a minimum in case of a collision. After hot-pressing the AlSi-boron steel shows excellent properties with high tensile strength, minimal spring back and also shows good protection against corrosion. 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
