    Abstract : The iron and steel industry emitted 8 % of all CO2 emissions in Sweden, 2011. Investigating alternative energy carriers is the purpose of this thesis. By pyrolyzing biomass, an energetic solid, gaseous and liquid (bio oil) fraction is obtained. READ MORE

  4. 2. Powder Bed Fusion – Laser Beam of Mg alloy WE43 : Establishing the process – structure – properties relationship

    Author : Hanna Nilsson Åhman; Cecilia Persson; Francesco D'Elia; Pelle Mellin; Eduard Hryha; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powder bed fusion - laser beam; additive manufacturing; magnesium; WE43; microstructure; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Powder bed fusion - laser beam (PBF-LB) of Mg alloy WE43 (Mg-4wt%Y-3wt%RE-Zr) has great potential for the development of future biodegradable metal implants, as well as aerospace lightweight materials. However, the work published thus far has mainly focused on obtaining a fully dense material, and the understanding of the relationship among the PBF-LB process parameters, structure and the resulting material properties remains limited.
