1. 1. Structural analysis of HZO thin film and electrode using X-ray diffraction

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

   Author : Elliot Winsnes; [2024]
   Keywords : HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

   Abstract : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. READ MORE

3. 2. The Effect of Temperature Gradients During Intercritical Annealing of Advanced High Strength Steels : Method Development for Experimental Streamlining

   University essay from KTH/Materialvetenskap

   Author : Helena Ek Jendrny; [2023]
   Keywords : AHSS; Gleeble; Intercritical annealing; Retained austenite; Medium Mn Steel; AHSS; Gleeble; interkritisk glödgning; austenit; Medium Mn stål;

   Abstract : The third-generation advanced high strength steels, AHSS, represent an opportunity for today’s steel development, where lighter materials with maintained strength and toughness are in demand. The unique properties of these materials often stem from a tailored microstructure. READ MORE

4. 3. Electrolytic Reduction of Iron Oxides in Molten Salt with a Mineralogical Investigation of Magnetite Ore of Tapuli

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Elina Fernö; [2023]
   Keywords : Iron reduction; trace element analysis on magnetite ore; molten salt electrolysis; sodium hydroxide electrolyte; NaOH; greenhouse gas; carbon dioxide; CO2; green ironmaking; Järnreduktion; spårelementanalys på magnetitmalm; smältelektrolys; elektrolys i natriumhydroxid; NaOH; elektrolyt; växthusgas; koldioxid; CO2; grön järnframställning;

   Abstract : This master's thesis covers an investigation of the reduction behavior of different iron oxides when electrolytically reduced with molten salt electrolysis (MSE). The tested iron oxides were wüstite (FeO), hematite (Fe2O3), magnetite (Fe3O4) and magnetite ore concentrate from the Tapuli deposit in Pajala, Norrbotten, Sweden. READ MORE

5. 4. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

   University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

   Author : Shivang Parmar; [2023]
   Keywords : Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

   Abstract : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. READ MORE

6. 5. Microstructure and Mechanical Investigation ofCarbides Particles Reinforced High AusteniticManganese Steel

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

   Author : Abderrahim Ait ouakrim; [2023]
   Keywords : Metal Matrix Composites MMCs ; Manganese steel; Carbides particles; Wear resistance;

   Abstract : The objective of this study was to produce a metal matrix composite (MMC). This compositematerial proves highly suitable for scenarios involving abrasive wear, owing to the exceptionalhardness of carbide particles, in conjunction with the remarkable ductility and capacity for workhardening found in Hadfield steel.
