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

   University essay from KTH/Hållfasthetslära

   Author : Love Englund; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

3. 2. High Temperature Tribology in Hot Stamping

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Evan Kurnia; [2019]
   Keywords : high temperature tribology; hot stamping; acoustic emission; condition monitoring; hardfacing;

   Abstract : Many automotive components are made of Al-Si coated ultra-high strength boron steel (UHSS) and are produced by hot stamping process. In this process, the workpiece is heated to an austenitizing temperature and is then formed and quenched simultaneously between the tools to achieve the desired shape and high strength. READ MORE

4. 3. Resistance Spot Welding of AlSi-coated Ultra High Strength Steel : An experimental study

   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

5. 4. Investigation of the mechanical performance of metal-composite joints

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Marc Olavide Rubio; [2017]
   Keywords : carbon fiber epoxy; AlSi-coated boron steel; metal-composite joints; double-cantilever beam test; end-notched flexural test; tensile test;

   Abstract : Composite materials are gaining the attention of several industries due to the high stiffness-to-weight and strength-to-weight ratios they offer. Especially in the automotive industry, demands on reduction of CO2 emissions is the major driving force towards lighter vehicles. READ MORE

6. 5. 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
