1. 1. Irradiation Embrittlement on a Core Shroud from Decommissioned BWR

   University essay from KTH/Fysik

   Author : Åsa Bjåland; [2023]
   Keywords : hardness; Vickers hardness test; ATT; yield strength; irradiation embrittlement; welds; hårdhet; Vickers hårdhetstest; ATT; sträckgräns; bestrålningsförsprödning; svetsar;

   Abstract : Irradiation embrittlement is a problematic issue for internal structures, such as acore shroud, in a light water reactor. It is characterized by decreased ductility andtoughness, and increased yield strength and hardening due to increased dislocations. READ MORE

3. 2. Characterization of Fiber Orientation and Weld Line Effects in Reinforced Plastics with Reduced CO2eq Emissions

   University essay from Jönköping University/JTH, Material och tillverkning

   Author : Anders Tolf; Markus Johannesson; [2022]
   Keywords : Fiber-reinforced plastics; GFRP; Reduced carbon dioxide equivalent materials; Experimental; Uniaxial tensile test; Uniform fiber orientation plate; Tensile strength; Fiber orientation; Weld line; Fracture analysis; Microscopy;

   Abstract : With increasing emphasis and regulations on the environmental footprint in industries, the integration of reduced carbon dioxide equivalent (CO2eq) plastic materials is desirable. Fiber-reinforced plastic materials mechanical properties differ with varying fiber orientations. READ MORE

4. 3. Modeling of Precipitation by Structural Phase-Field Crystal Method

   University essay from Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

   Author : Jacob Holmberg-Kasa; [2021]
   Keywords : strain-age cracking; SAC; structural phase-field crystal; XPFC; nickel-based alloys; precipitation;

   Abstract : Nickel-based alloys are used in components such gas turbines within the aerospace industry and electric power generation due to its high tensile, rapture and creep strength. Increasing the efficiency of gas turbines are crucial to reduce emissions within the aerospace industry and increasing power gain for electric power generation. READ MORE

5. 4. Characterization of the ethylene-vinyl acetate copolymer and the influencing parameters of the weld in intravaginal rings

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Ludwig Kaindl; [2020]
   Keywords : Ethylene-vinyl acetate; Intravaginal rings; DSC; Thermal properties EVA; Welding; Pharmaceutical Technology; Läkemedelsteknologi; Technology and Engineering;

   Abstract : The aim of this thesis was to characterize the mechanical and thermal properties of three different ethylene vinyl acetate (EVA) polymers with varying vinyl acetate (VAc) content and to investigate the influential parameters when welding the polymer into intravaginal rings. A second purpose in this study was to compare two different produced EVA polymers with the same VAc content to find thermal and structural differences. READ MORE

6. 5. Evaluation of material properties after laser welding on ductile cast iron

   University essay from KTH/Materialvetenskap

   Author : Olivia Taivalkoski; [2019]
   Keywords : Laser welding; ductile cast iron;

   Abstract : Scania wants to lower the weight of their trucks, including the goal to reduce the carbon dioxide emissions, and one way to do that is to use laser welding instead of fastenings.This bachelor thesis work is about laser welding of ductile cast iron, or spheroidal graphite cast iron or nodular cast iron, to QT-steels and case hardening steel and evaluation of the mechanical properties of the weld.
