    University essay from KTH/Materialvetenskap

    Author : Kristofer Hjelmtorp; [2019]
    Keywords : RSW; resistance spot welding; usibor; boron steel;

    Abstract : 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. READ MORE

  2. 2. Metallurgical investigation in weldability of Aluminium Silicon coated boron steel with different coating thickness.

    University essay from KTH/Materialvetenskap

    Author : Rickard Aldén; [2015]
    Keywords : boron steel; AlSi coating; weldability; hot stamping; phase formation;

    Abstract : 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. READ MORE

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

    University essay from KTH/Lättkonstruktioner

    Author : Adam Häggqvist; [2015]
    Keywords : ;

    Abstract : 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. READ MORE
