1. 1. Precipitation analysis in bearing steel Hybrid 60

   University essay from KTH/Materialvetenskap

   Author : Rebecca Rosén; [2023]
   Keywords : martensitic steel; secondary hardening; precipitation; PRISMA; martensitiskt stål; sekundärhärdning; utskiljning; PRISMA;

   Abstract : New materials are always being developed to get the best properties possible where needed. The way to create these materials and test them is also developing. When it comes to high-strength steels, a martensitic microstructure is a common choice. READ MORE

3. 2. Non-Linear strain paths in Sheet Metal Forming

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Anton Eriksson; [2021]
   Keywords : Sheet metal forming SMF ; Non-Linear strain path NLSP ; Test procedures; Failure models; Finite Element FE ; Plåtformning; Icke-linjära töjningsbanor; Test procedurer; brott model; Finita Element FE .;

   Abstract : Today's automotive requirements have resulted in complex Sheet Metal Forming (SMF) processes of Sheet Metal (SM) with reduced formability, and thus it is crucial to be able to predict formability accurately to prevent material failure during SMF. Formability predictions today utilize Forming Limit Curves (FLC)s in Finite Element Analysis (FEA), but  FLCs are not valid for the Non-Linear Strain Paths (NLSP)s generated during SMF. READ MORE

4. 3. Corrosion studies on multicomponent TiZrNbTa thin films

   University essay from Uppsala universitet/Strukturkemi

   Author : Asker Jarlöv; [2020]
   Keywords : Corrosion resistance; Multicomponent thin-film; High entropy alloy; TiZrNbTa; Bipolar plates; Magnetron sputtering;

   Abstract : The goal of this work was to evaluate the electrochemical properties of TiZrNbTa thin films deposited by magnetron sputtering using an industrial physical vapor deposition system. Samples were deposited on both Si(001) and 316L stainless steel. READ MORE

5. 4. Fracture prediction of stretched shear cut edges in sheets made of Dual-Phase steel

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Johannes Falk; [2017]
   Keywords : Strain; DP steel; Dual-phase steel; Autoform; Aramis; Fracture strain; Advanced High Strength Steels; AHSS; Fracture prediction;

   Abstract : Dual-Phase (DP) steels, part of the group of Advanced High Strength Steels (AHSS), are used by car manufactures due to its large strength to weight ratio. The high strength of the DP steel does have a negative impact on the formability during sheet metal forming and stretch forming, e.g. READ MORE

6. 5. Finite Element Simulation of Crash Testing of Self-Piercing Rivet Joints, Peel Specimen

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Väg- och vattenbyggnad (CI)

   Author : Christian Westerberg; [2002]
   Keywords : Technology and Engineering;

   Abstract : Within the automotive industry today, companies save significant amounts of money through computer simulations. Mathematics through numerical methods becomes important when as in this case the investigation is done with the Finite Element Method (FEM). A self-pierced rivet (SPR) joint specimen in a T-peel case is studied. READ MORE
