1. 1. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

   University essay from Jönköping University/JTH, Material och tillverkning

   Author : Anton Rolseth; [2023]
   Keywords : Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

   Abstract : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. READ MORE

3. 2. The magnetic field of phi Draconis

   University essay from Uppsala universitet/Observationell astrofysik

   Author : Nikolaos Papakonstantinou; [2022]
   Keywords : stars: atmospheres – stars: chemically peculiar – stars: magnetic field – stars: starspots – stars: individual: phi Dra;

   Abstract : Within this past decade, advances in spectropolarimetric analyses allowed mapping surface characteristics of nearby non-resolved stars with unique characteristics. In this study, we attempt mapping of the magnetic field structure and surface distribution of elements for such a star, the magnetic Ap star phi Dra. READ MORE

4. 3. Improvement of Pt-based catalyst supported on CeZrO2 used for the high-temperature water-gas shift reaction

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Milda Grikainyte; [2022]
   Keywords : Water-gas shift; catalyst; chemical engineering; Chemistry;

   Abstract : The iron-chromium (Fe/Cr) catalyst is used for high-temperature water-gas shift (HT WGS) reaction. A major concern using the Fe/Cr catalyst is that it contains hexavalent chromium (Cr+6) which is a potent carcinogen causing health and environmental issues. READ MORE

5. 4. Thermodynamic modelling ofmartensite start temperature in commercial steels

   University essay from KTH/Materialvetenskap

   Author : Arun Kumar Gulapura Hanumantharaju; [2018]
   Keywords : Martensite start temperature; Thermodynamic modelling; Austenite grain size; Epsilon martensite; CALPHAD;

   Abstract : Firstly, an existing thermodynamic model for the predicting of martensite start temperature of commercial steels has been improved to include more elements such as N, Si, V, Mo, Nb, W, Ti, Al, Cu, Co, B, P and S and their corresponding composition ranges for Martensitic transformation. The predicting ability of the existing model is improved considerably by critical assessment of different binary and ternary systems i. READ MORE

6. 5. Modelling of spinodal decomposition in the binary Fe-Cr system

   University essay from KTH/Materialvetenskap

   Author : Viking Roosmark; [2016]
   Keywords : SPINODAL DECOMPOSITION; FE-CR; DIFFUSION; FERRITIC STAINLESS STEAL;

   Abstract : Spinodal decomposition is a phenomenon which hinders the usage of ferrite containing steels under certain conditions. With a better understanding and knowledge of spinodal decomposition new ferritic and duplex stainless steels could be designed. The project is divided into two parts, an experimental part and a theoretical part. READ MORE
