  4. 2. Fatigue and Corrosion Fatigue Fracture of a Plasma Nitrided, Laser Hardened, and Galvanized B-Mn Steel

    Author : Pedro De la Cruz Rodrígues; Birger Karlsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Fundamental and technological aspects of fatigue and fracture of conventional and advanced material are topics of primary importance to the development of materials science and engineering. Surface treatments have been established to improve the surface properties of material against surface phenomenon such as wear, corrosion, fatigue and corrosion fatigue. READ MORE

  5. 3. Toughness of Tool Steel

    Author : Henrik Jesperson; Håkan Engqvist; Birger Karlsson; Uppsala universitet; []
    Keywords : Toughness; Tool Steel; Heat Treatment; Temperature; Energy absorption; Impact Testing; Fracture Toughness Testing; Non-metallic Inclusions; Carbides; Nitrides; Statistics; TECHNOLOGY; TEKNIKVETENSKAP; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Toughness is the ability to resist tensile stresses in the presence of a notch or crack. Sometimes gross cracking of industrial tools, mould or dies, occurs due to insufficient toughness. As the economic consequences of the gross cracking are serious, the toughness of industrial tool material, generally tool steel, is of paramount importance. READ MORE

  6. 4. Tool steel for tool holder applications : microstructure and mechanical properties

    Author : Anna Medvedeva; Jens Bergström; Birger Karlsson; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steel; tool holder; microstructure; mechanical properties; machinability; Materials science; Teknisk materialvetenskap;

    Abstract : Large improvements in cutting tool design and technology, including the application of advanced surface engineering treatments on the cemented carbide insert, have been achieved in the last decades to enhance tool performance. However, the problem of improving the tool body material is not adequately studied. READ MORE

  7. 5. Characteristics of cast aluminium-silicon alloys : microstructures and mechanical properties

    Author : Salem Seifeddine; Birger Karlsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium; Mocrostructure; Porosity; Tensile properties; Modelling; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik; Materials science;

    Abstract : Applications of aluminium alloys are spreading in many industrial fields due to the excellent combination of castability, mechanical performance and lightness assured by such material. This project aims to establish a methodology in bringing the foundry process closer to the casting designer, and thereby leading to a more reliable and more optimised design. READ MORE
