  3. 2. Precipitation in Advanced Stainless Steels

    Författare :Niklas Holländer Pettersson; Annika Borgenstam; Sten Wessman; Joacim Hagström; Jacques Charles; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Advanced stainless steels often suffer from complex precipitation behaviour due to the high levels of alloying elements needed to obtain their attractive properties. This demands a correct handling of the material to avoid formation of harmful phases during production, manufacturing and service. LÄS MER

  4. 3. 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
