  1. 36. Application of some modern analytical techniques for investigations of non-metallic inclusions in steel samples

    University essay from KTH/Materialvetenskap

    Author : Wan Zhiyue; [2018]
    Keywords : Non-metallic Inclusions; Electrolytic Extraction; Fractional Gas Analysis; Zirconium Addition; Calcium Treatment;

    Abstract : The non-metallic inclusions (NMI) have large influence on steel properties. Therefore, evaluation of inclusion size, number, composition and morphology by using modern analytical techniques are very important for control of steel production and steel quality. Three dimensional analysis method of electrolytic extraction is applied in this work. READ MORE

  2. 37. Investigation of wear behavior of different sliding bearing materials in an alkaline environment

    University essay from

    Author : Martina Ottosson; [2018]
    Keywords : wear; tribology; alkaline; sliding bearing;

    Abstract : In sliding bearing wear is a very common problem and can be affected by several factors. The wear in a bearing can lead to total failure of the component and lower the lifetime. In a sliding bearing used in a machine in the pulp and paper industry large wear has been detected, but no clear evidence of what the wear depends on. READ MORE

  3. 38. Effect of oxygen concentration in build chamber during laser metal deposition of Ti-64 wire

    University essay from KTH/Materialvetenskap

    Author : Eyvind Engblom; [2018]
    Keywords : additive manufacturing; laser metal deposition; alpha-case; titanium; wire;

    Abstract : Additive manufacturing of titanium and other metals is a rapidly growing field that could potentially improve component manufacturing through optimization of geometries, less material waste and fewer process steps. Although powder-based additive manufacturing processes have so far been predominant, methods using a wire as feedstock has gained popularity due to faster deposition rates and lower porosity in deposited material.

  4. 39. Interaction Effect of Filler Material on Fungal Biomass Activity for Heavy Metal Biosorption in Stormwater

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

    Author : Robert Peterson; [2018]
    Keywords : Heavy metals; Biosorption; Fungal biomass; Serial optimisation;

    Abstract : In the wake of ever more occurring and evident consequences brought by climate change such as droughts and an increasing world population, a responsible use and handling of freshwater has never been as important as before. Stormwater is more than often not treated and simply released back in nature with any kind of pollution it has collected on its way, one of which being heavy metals. READ MORE

  5. 40. Fines Content and Density Effects on Tailings Behaviour : A Laboratory Study on Geotechnical Properties

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Viktor Wiklund; [2018]
    Keywords : strength; compressibility; permeability; anrikningssand; hållfasthet; konsolidering; permeabilitet;

    Abstract : Tailings are a rest product from the extraction of metals and minerals, and is therefore produced in large volumes by all mining companies. One common way to store tailings material is to deposit it as a hydraulic slurry on a tailings impoundment, where the tailings are held in place by tailings dams. READ MORE
