  1. 1. Additive manufacturing of fused silica glass

    Author : Pawel Maniewski; Michael Fokine; Fredrik Laurell; Daniel Milanese; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser cladding; 3d printing; additive manufacturing; glass; fused silica; laser; scattering; silica; Optik och fotonik; Optics and Photonics; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Additive Manufacturing, of both metals and polymers, has seen rapid development in recent years, whereas the progress in glass has been rather slow. Today, glass can be considered the last frontier without a specialized 3D printing method available. READ MORE

  3. 3. Tribology in Metal Working

    Author : Maria Nilsson; Staffan Jacobson; Mikael Olsson; Magnus Jarl; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; friction; wear; metal working; coatings; wire drawing; hot work rolls; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials; tribology; Steel Forming and Surface Engineering; Stålformning och ytteknik;

    Abstract : This thesis focuses on the tribological performance of tool surfaces in two steel working operations, namely wire drawing and hot rolling. In all forming operations dimensions and surface finish of the products are of utmost importance. READ MORE

  4. 4. Metal release from stainless steels and the pure metals in different media

    Author : Gunilla Herting; Inger Odnevall Wallinder; Lena Wegrelius; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; stainless steel; iron; chromium; nickel; metal release; artificial rain; synthetic body fluid; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : This study has been triggered by the fact that stainless steel is being increasingly used in new applications, where possible environmental effects may be a matter of concern. When stainless steel is exposed to a given environment, a key issue is the release of small amounts of the main alloying elements iron, chromium, nickel and molybdenum. READ MORE

  5. 5. Challenges in Resistance Welding of Ultra High Strength Steels

    Author : Erik Tolf; Arne Melander; Zuheir Barsoum; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resistance welding; spot welding; surface cracks; nut welding; UHSS; projection welding; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Increasing the use of Ultra High Strength Steels (UHSS) in vehicle bodystructures is important for reducing weight and cutting CO2 emissions. This thesis investigates challenges in resistance welding that can be a barrier to implementing UHSS as a replacement for low strength steels in vehicle structures. READ MORE
