  1. 6. Reduction of iron oxide by hydrogen studied using environmental transmission electron microscopy

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : David Wahlqvist; [2020]
    Keywords : Transmission Electron Microscopy; Electron Diffraction; Iron Oxide; Reduction; Iron; Environmental Transmission Electron Microscopy; ETEM; Materials chemistry; Materialkemi; Chemistry;

    Abstract : This thesis aims to explore how the reduction of iron oxide by hydrogen should be explored in an environmental transmission electron microscope (ETEM). This is done by performing a series of reduction attempts in the ETEM at nCHREM, Lund University, and exploring how the ETEM conditions are different from those used commercially. READ MORE

  3. 7. Optimization of Rare Earth Metals (REM) addition in high temperature stainless steel grade 253MA.

    University essay from KTH/Materialvetenskap

    Author : Bharath Vasudev Rangavittal; [2019]
    Keywords : REM addition; non-metallic inclusion; oxidation; austenitic; optimization;

    Abstract : The focus of this thesis work is to optimize rare earth metal (REM) addition in Therma 253MA, an austenitic stainless-steel grade in order to get a good trade-off between oxidation resistance property and the amount of big REM inclusions formed. Big REM inclusions are detrimental to material properties and REM is required to be dissolved in the matrix for improving the oxidation resistance. READ MORE

  4. 8. Microscopy techniques for studying polymer-polymer blends

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sandra Mattsson; [2019]
    Keywords : CLEM; correlative light and electron microscopy; correlative microscopy; fluorescence microscopy; scanning electron microscopy; phase contrast microscopy; polymer blend; morphology; super yellow; PEO; poly ethylene oxide ; CLEM; korrelativ ljus- och elektronmikroskopi; korrelativ mikroskopi; fluorescensmikroskopi; svepelektronmikroskopi; faskontrastsmikroskopi; polymerblandning; morfologi; super yellow; PEO; poly etylenoxid ;

    Abstract : Semiconductors are used in many electronic applications, for example diodes, solar cells and transistors. Typically, semiconductors are inorganic materials, such as silicon and gallium arsenide, but lately more research and development has been devoted to organic semiconductors, for example semiconducting polymers.

  5. 9. Ablation of Si with femtosecond laser

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Stefano Prevosti; [2016]
    Keywords : ;

    Abstract : Femtosecond laser ablation of different materials is becoming more and more important in micro- and nanomachining fields. The cutting precision and cost-effectiveness related to this method are turning it into a valid alternative to traditional methods. READ MORE

  6. 10. Titanium alloys Mechanical properties and microstructure transformation

    University essay from Lunds universitet/Fysiska institutionen

    Author : Martin Olsson; [2016]
    Keywords : Physics and Astronomy;

    Abstract : Abstract The aim of the project is to determine the mechanical properties and the microstructure with a to b transformation of the titanium alloy Ti-6Al-4V. The experiments made were tensile tests at temperatures 20, 400 and 800C and SEM images before and after inductive methods. READ MORE
