  1. 16. Ab inito calculation of the formation energy of the sigma phases at 1000 Kelvin : With a five sublattice model for the ternary Iron-Chromium-Nickel system

    University essay from KTH/Materialvetenskap

    Author : Fabian Mathias Veid; [2022]
    Keywords : ;

    Abstract : This project investigates the σ-phase formation energy at 1000 Kelvin using Exact Muffin TIn Orbital (EMTO) method and considers the disordered local moment approach to handle the paramagnetism in a self-consistent manner. The sigma phase is detrimental and causes embrittlement when it occurs primarily in stainless steel and superalloys with Iron (Fe) and Chromium (Cr), which is why it is necessary to understand it better and therefore avoid it.

  3. 17. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : William Tönnberg; [2022]
    Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

  4. 18. Techniques for characterization and quantification analysis of foulant deposition in Alfa Laval’s high-speed separators : A literature study

    University essay from

    Author : Mwansa Benaya; Henrik Dahlén; Emil Axelsson; Cassandra Liljekvist; Maja Nordell; [2022]
    Keywords : Dairy foulant; Marine foulant; Characterization; Quantification; Stainless steel; surface; analysis;

    Abstract : Alfa Laval is a global company that provides solutions, products, and services for industry, such as high-speed separators for marine and food-application. Foulant deposition on the stainless-steel surfaces of Alfa Laval’s high-speed separators has shown to result in lowering of the separation efficiency. READ MORE

  5. 19. Fracture analysis of tensile- and fatigue failure for perforated and wedge wire structures

    University essay from

    Author : David Barjosef; Alexander Austen Öhrn; [2022]
    Keywords : ;

    Abstract : In the effort to produce more durable filters and understand their mechanical failure, this study presents distinctive indicators on the cause of failure for welded perforated- and wedge wire sheets in 316L stainless steel, super duplex UR52N stainless steel and grade 2 titanium. The study achieves this by fracture analysis on specimens from tensile strength- and fatigue testing. READ MORE

  6. 20. Design of an Autonomous underwater drone for achieving efficiency in the operation of the sensor package during monitoring of water bodies

    University essay from Blekinge Tekniska Högskola

    Author : Muaz Abdul Muti; [2022]
    Keywords : Autonomous; drone; sensor; stainless steel;

    Abstract : Background: the process of water quality monitoring is a critical quality assurance process. However, conventional methods include monitoring by a team of divers going to different depths to collect water samples. This method is expensive, time-consuming, and can lead to adverse consequences like a fatality. READ MORE
