1. 21. Comparative investigation of micromechanisms of plastic deformation by in-situ tensile tests of highly textured 316L steel

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Subhani Kumarasinghe; [2022]
   Keywords : Additive manufacturing; texture control; plastic deformation;

   Abstract : Additive manufacturing (AM) is identified as one of the best techniques in manufacturing components addressing most of the current challenges including material scarcity, design complexity, material compatibility, etc. Stainless steel 316L is one of the promising material candidates in AM due to its extraordinary properties that are useful in a wide variety of industries.

3. 22. Evaluation of Coefficient of Friction in Oblique Helmet Impacts: An Experimental and Numerical Study

   University essay from KTH/Hållfasthetslära

   Author : Philip Singh; [2022]
   Keywords : FE model; friction; helmet impact; LS-DYNA; FE-modell; friktion; hjälmislag; LS-DYNA;

   Abstract : The focus of this thesis was to increase the knowledge in the area of "dynamic friction" during oblique helmet impacts, both experimentally and numerically. Physical experiments have been performed with multiple helmets, different angles of the anvil and different surface materials, with results of impact forces from the anvil and accelerations of the head.

4. 23. Analysis of hot workability in 316L steel using ductile fracture criterions

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

   Author : Viktor Strid; [2022]
   Keywords : Ductile fracture criterion; Finite Element Method; Hot working; 316L Stainless Steel; Fracture Modeling; Gleeble; Hot deformation;

   Abstract : The focus of this thesis is to develop a simulation model for predicting ductile fractures during hot working at Alleima. The main fracture mechanism in these conditions is ductile fracture by void coalescence. The ductile fractures are caused by the linking of voids that appear when there is large plastic deformation near second-phase particles. READ MORE

5. 24. An Industrial Application of Semi-supervised techniques for automatic surface inspection of stainless steel. : Are pseudo-labeling and consistency regularization effective in a real industrial context?

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Mattia Zoffoli; [2022]
   Keywords : Deep Learning; Computer Vision; Semi-Supervised Learning; Automatic Inspection; Stainless Steel; Djupt lärande; datorseende; Semi-övervakat lärande; Automatisk inspektion; Rostfritt stål;

   Abstract : Recent developments in the field of Semi-Supervised Learning are working to avoid the bottleneck of data labeling. This can be achieved by leveraging unlabeled data to limit the amount of labeled data needed for training deep learning models. READ MORE

6. 25. Precipitation behavior of the super austenitic stainless steel SANICRO® 35 and the effect on impact toughness and pitting corrosion resistance

   University essay from KTH/Materialvetenskap

   Author : Shunyi Li; [2022]
   Keywords : Super austenitic stainless steel; solid phase transformation; TTT diagram; impact toughness; critical pitting temperature; TC PRISMA simulation; Superaustenitiskt rostfritt stål; fastfasomvandling; TTT-diagram; slaghållfasthet; kritisk punktfrätningstemperatur; TC PRISMA simulering;

   Abstract : This research extended the knowledge of the solid phase transformation and the resulting influence on impact toughness and pitting corrosion resistance in super austenitic stainless steel (SASS) SANICRO® 35. A time-temperature-transformation diagram (TTT diagram) was assembled by performing isothermal heat treatments in the temperature range of 650-1050 °C for different periods of time, ranging from 5 min to 500 min.
