1. 1. 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

3. 2. The effects of spinal implant wear debris particles

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Cecilia Thomas; Eslam El Ammarin; [2021]
   Keywords : spine; implant; wear; debris; particles; ryggimplantat; implantatpartiklar; partiklar; implantat;

   Abstract : The goal of this literature study was to study the effects of spinal implant wear debris particles on the body in general, and on microglia cells in particular. The method of the literature study was searching for scientific peer-reviewed papers on the topic.  Spinal implants are used to fix spinal problems such as deformities or injuries. READ MORE

4. 3. Extraction Replicas of Common Engineering Alloys for Analysis of Small Precipitates

   University essay from KTH/Materialvetenskap

   Author : Monika Rolinska; [2020]
   Keywords : Extraction replica; transmission electron microscopy; materials characterization; precipitation; Extraktionsrepliker; transmissionselektronmikroskopi; materialkaraktarisering; utskiljningar;

   Abstract : Characterization of small precipitates is important for development of new alloys. One inherent  difficulty  in  characterisation  of  small  precipitates  with  electron microscopy techniques  while  the  particles  are  embedded  in  the  matrix,  is  that the surrounding bulk material will contribute to the analysed signal- limiting, for example, the quantification of the composition of particles.

5. 4. Thermal Stability of Titanium and Niobium Stabilized Stainless Steel

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Oskar Darselius Berg; [2020]
   Keywords : Technology and Engineering;

   Abstract : This master thesis examined the microstructure after heat treatments in stainless steel, two conventional stainless steel (304 and 316) and two novel high temperature stainless steel. These stainless steels are for the use in high temperature heat exchangers for extended temperature range. READ MORE

6. 5. Design Investigation into Liquid Oxygen Vaporisation Systems : Atomisation and Heat Loads

   University essay from KTH/Energiteknik

   Author : Borbala Bernus; [2020]
   Keywords : LOx; gasification; two-phase CFD simulation; rapid oxidation; rocket; cryogenic; hybrid; atomisation; LOx; förgasning; 2-fas CFD-simulering; snabb oxidation; raket; kryogen; hybrid; atomisering;

   Abstract : Computational Fluid Dynamics (CFD) simulations are presented within this study for super-cooled liquid oxygen atomisation and gasification in a subcritical chamber operating at 1MPa. Relatively low cost simulation techniques have been used and their accuracy evaluated. READ MORE
