  1. 16. Strategies for regional deployment of hydrogen infrastructure : The case of North Rhine-Westphalia, Germany

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Roberto Di Molfetta; [2022]
    Keywords : Hydrogen; Infrastructure rollout; Supply chain pathways; Mobility; Hydrogen buses.;

    Abstract : In response to the growing urge towards decarbonisation, more and more initiatives have been set to reduce and/or compensate the level of CO2 (carbon dioxide) emitted by human activities, which is one of the main responsible of the incumbent threats of “global warming” and “climate change”. “Climate neutrality by 2050” has become a decisive topic for political agendas worldwide and, against that background, the hydrogen economy can play a significant role.

  3. 17. Developing a supervised machine learning model for an optimised aluminium addition based on historical data analytics, for clean steelmaking

    University essay from KTH/Materialvetenskap

    Author : Arun Kumar Thakur; [2022]
    Keywords : Clean steelmaking; Data analytics; De-oxidation; Machine learning; Ren ståltillverkning; Dataanalys; Deoxidation; Maskininlärning;

    Abstract : De-oxidation is an important process in clean steelmaking. Al (Aluminium) is mainly used as de-oxidant and controls the final oxygen content and impact the sulphur removal in steel. Adding optimum amount of Al is critical for steel cleanliness and to reduce cost. READ MORE

  4. 18. Desulphurization capacity of ladle slags for tool steels

    University essay from KTH/Materialvetenskap

    Author : Sixten Johansson; Elliot Nilstam; [2022]
    Keywords : ;

    Abstract : Steel quality is in direct correlation with the desulphurization process, meaning the removal of sulphur. A good desulphurization process greatly improves the mechanical properties among others, and is essential for obtaining higher quality steel. READ MORE

  5. 19. An investigation of the design of cylinderical steel tanks modelled according to EN14015 and according to the Eurocodes

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Yonas Gebre; [2022]
    Keywords : Keywords: Steel tank; Wind; Snow; FEM; Shell buckling; Non-linear analysis;

    Abstract : Abstract Storage tanks are above or below ground vessels for storing chemicals, petroleum and other liquid products. Above ground vertical cylindrical shells are typically thin walled structures prone to buckling and lose their stability especially when they are empty or have lower fluid level due to external loads.

  6. 20. Mechanical and tribological characterization of additive manufactured Co-alloyed tool steels aimed for cutting tool bodies

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Jijesh Rajan; [2022]
    Keywords : Maraging steels; Selective laser melting; microstructure; wear; Modified 18Ni300; Osprey MAR;

    Abstract : A drill tool body operates under tough cutting conditions where it is subjected to severe rubbing at the drill flute margin by the sliding chips. The tool wear caused by the contact stresses of the high-speed sliding chips is one of the common damage mechanisms observed in drill tool bodies. READ MORE
