  1. 6. Raman spectroscopy for characterization of soot and other carbonaceous materials

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

    Author : Jonatan Henriksson; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Raman spectroscopy is well known as a method that can be used to study the structural characteristics of carbon materials such as soot and carbon black. In this work, a Raman spectroscopy setup was used to record spectra of various carbonaceous samples under different experimental conditions. READ MORE

  3. 7. Residual stresses and distortions in austenitic stainless steel 316L specimens manufactured by Selective Laser Melting

    University essay from Högskolan Väst/Avdelningen för svetsteknologi (SV)

    Author : Henrik Nöbauer; [2018]
    Keywords : Residual Stresses; Distortions; SLM; Selective Laser Melting; 316L; X-ray diffraction; XRD; ESPI; Hole drilling;

    Abstract : Residual stresses are one of the major challenges in additive manufacturing of metallic materials today. They are induced during manufacturing because of the rapid local heating and cooling and may cause distortions, cracking and delamination between layers. READ MORE

  4. 8. Development of method for processing brittle-hard materials using Laser Metal Deposition (LMD)

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

    Author : Alejandro Simó Vesperinas; [2018]
    Keywords : Additive Manufacturing AM ; Laser Metal Deposition LMD ; Direct Metal Deposition DMD ; High-temperature materials; Mo-Si-B alloy; Residual stress; Cracks;

    Abstract : New materials capable of operating at ultra-high temperatures in gas turbine engines are highly desired. Materials such as silicides of refractory metals present great potential to substitute single crystal nickel-based superalloys. READ MORE

  5. 9. Optimization of the AdBlue e vaporation module for Scania V8 engines

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Mattia Antoniotti; [2017]
    Keywords : CR; evaporation unit; urea deposits; heat fins; Urea; förångningsmodulen; ureaavlagringar; rörflänsar;

    Abstract : The aftertreatment techniques introduced to follow the emission legislations require a constant improvement process to comply with the gradually more stringent demands. SCR is the system used nowadays to deal with NOx emissions in most heavy-duty vehicles. READ MORE

  6. 10. Shape Distortion Analysis of Self-Reinforced Poly(ethylene terephthalate) Composites : The PETrifying reality!

    University essay from KTH/Lättkonstruktioner

    Author : Calle Eliasson; [2016]
    Keywords : ;

    Abstract : Composite components with a V-shaped geometry have been manufactured through compression moulding of fabrics based on self-reinforced poly(ethylene terephthalate). The fabrics were subjected to a set of predetermined degrees of stretching during manufacturing with the intent to investigate its effects on shape distortions in terms of spring-in and warping.
