    • Behavior of Al4C3 Particles During Flotation and Sedimentation in Aluminum Melts 

      Gökelma, Mertol; Aarnæs, Trygve Storm; Maier, Jürgen; F. Renkel, Maria; Ekstrøm, Kai Erik; Friedrich, Bernd; Tranell, Gabriella (Peer reviewed; Journal article, 2021)
      Al4C3 particles form during the primary production of aluminum via molten salt electrolysis due to the carbon solubility and direct contact between bath, metal, and carbon anodes. Additional Al4C3 may form during melt ...

    • Behaviour of Aluminium Carbide in Al-melts during Re-melting 

      Gökelma, Mertol; Aarnæs, Trygve Storm; Maier, Jürgen; Friedrich, Bernd; Tranell, Gabriella (Journal article; Peer reviewed, 2019)
      The presence of non-metallic inclusions in aluminium has become a more critical issue with increasing demands on surface quality and low final wall thicknesses of products. Aluminium carbide particles form during the primary ...

    • Characteristics of TI6AL4V powders recycled from turnings via the HDH technique 

      Gökelma, Mertol; Celik, Dilara; Tazegul, Onur; Cimenoglu, Huseyin; Friedrich, Bernd (Journal article; Peer reviewed, 2018)
      The objective of this research is for Ti6Al4V alloy turnings, generated during the machining of implants, to produce powders for the fabrication of Ti base coating via the cold spray method. In order to decrease the cost ...

    • Effects of Compaction and Thermal Pre‑treatments on Generation of Dross and Off‑Gases in Aluminium Recycling 

      Vallejo Olivares, Alicia; Gertjegerdes, Tom; Høgåsen, Solveig; Friedrich, Bernd; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2023)
      Organic coatings are a challenge for aluminium packaging recycling since they tend to increase the re-melting metal losses. A solution is de-coating the scrap via a thermal pre-treatment to burn-off the organics before ...

    • Shape Factor Effect on Inclusion Sedimentation in Aluminum Melts 

      Gökelma, Mertol; Einarsrud, Kristian Etienne; Tranell, Gabriella; Friedrich, Bernd (Journal article; Peer reviewed, 2020)
      The quality requirements of aluminum products are steadily increasing, and the presence of non-metallic inclusions have a large impact on the quality of aluminum products. Sedimentation is a widely applied technique to ...

    • Transformation of Iron (III) Nitrate from an Aerosol by Ultrasonic Spray Pyrolysis and Hydrogen Reduction 

      Stopic, Srecko; Hounsinou, Ayadjenou Humphrey; Stéphane, Koffi Aka; Volkov Husovic, Tatjana; Emil Kaya, Elif; Friedrich, Bernd (Journal article; Peer reviewed, 2023)
      Due to their unique properties, iron nanoparticles find diverse applications across various fields, including catalysis, electronics, wastewater treatment, and energy storage. Nano-iron particles are mostly sub-micrometer ...
