    Sammanfattning : There is a general consensus that education is crucial for achieving sustainable development. Education for sustainable development aims to foster citizens capable of participating independently and actively in creating a sustainable future. LÄS MER

  3. 2. Thermal Stability and Mechanical Properties of Bainitic Steel

    Författare :Adam Ståhlkrantz; Annika Borgenstam; Peter Hedström; Niklas Sarius; Joacim Hagström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bainite; Austempering; Low alloyed steel; Tempering; Variant pairing; Material characterization; Metallurgical process science; Metallurgisk processvetenskap; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : For material design it is important to understand and establish the relations between the processing of the steel, the resulting microstructure and how that correlate to the properties of the steel. The main focus of this thesis has been to increase this knowledge for low alloy bainitic steels with medium to high carbon content. LÄS MER

  4. 3. Sustainable Biobased Protein Superabsorbents from Agricultural Co-Products

    Författare :Antonio Jose Capezza; Mikael S. Hedenqvist; Eva Johansson; Antonio Guerrero; KTH; Sveriges lantbruksuniversitet; []
