  1. 1. Microstructural and Micro-Mechanical Characterization of As-built and Heat-treated samples of HASTELLOY X produced by Laser Powder Bed Fusion Process

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Onimisi Sanni; [2022]
    Keywords : As-built Hastelloy X blocks; Laser powder bed fusion LPBF ; Solution heat-treatment; Disrupted epitaxial growth; Melt Pool Boundaries MPB ; Grain Boundaries GB ; Precipitates; In-situ microtensile testing; microhardness; Mechanical properties; Twin grain boundary fractions;

    Abstract : Microstructure and micro-mechanical characterization of as-built and heat-treated samples of Hastelloy X produced by laser powder bed fusion (LPBF) process has been carried out in this study. As-built LPBF blocks were solution heat-treated at 1177°C and 1220°C followed by fast cooling. READ MORE

  3. 2. In Situ Heating During XRD Measurements as a Method to Study Recrystallisation of Aluminium Alloy AA3003

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Louise Bäckström; [2018]
    Keywords : In situ XRD; in situ heat treatment; recrystallisation; rolled aluminium; AA3003;

    Abstract : Recrystallisation is an important topic in the metal industry since the process may drastically alter the properties of the materials subjected to it. By controlling the recrystallisation process, the material properties can be adjusted as desired, which could lead to stronger materials and hence lighter constructions, decreasing our material consumption.

  4. 3. Thermodynamic Equilibrium Prediction of Corrosion Tendency in Fluidized-Bed Combustion of Solid Waste

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Aida Hosseinian; [2017]
    Keywords : Waste to Energy; Fluidized Bed Boiler; Combustion; Corrosion; Factsage; Chemical Fractionation; Waste-derived Fuel;

    Abstract : Global warming and air pollution are two issues of greatest concerns to human life in recent years. Environmental concerns and econimal/political independency of fossil fuels have been the driving force of developing interest in renewable resources of energy for many countries. READ MORE

  5. 4. Thermal Stability of Amorphous MoSiZr Thin Films

    University essay from Uppsala universitet/Materialfysik

    Author : Maciej Kaplan; [2016]
    Keywords : amorphous metals; metallic glasses; thermal stability; thin films; crystallisation temperature;

    Abstract : Metallic glass is a class of materials which have a disordered structure of atoms, due to this, glasses lack grains and grain boundaries, which are present in their crystalline counterparts. Metallic glasses have many interesting properties worth investigating, such as high corrosion resistance or high mechanical strength. READ MORE

  6. 5. Processintern metananrikning : energikartläggning och efterbehandling av svepgas

    University essay from SLU/Dept. of Energy and Technology

    Author : Ulf Hävermark; [2016]
    Keywords : biogas; småskalig; uppgradering; kväve; energibalans; ammoniak;

    Abstract : Small scale biogas plants (max digester volume 1000 m3) in Sweden produced in average 1.26 GWh per plant in 2014. Most of the biogas was used for combined heat and power production. The relatively cheap electricity in Sweden makes this a low profit business. READ MORE
