  2. 1. As-cast AZ91D Magnesium Alloy Properties- Effect of Microstructure and Temperature

    Author : Hoda Dini; Anders Jarfors; Nils-Eric Andersson; Uta Klement; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnesium alloys; As-cast; AZ91D; Mechanical properties; Microstructural scale effect; Physical modelling;

    Abstract : Magnesium and magnesium alloys are used in a wide variety of structural applications including automotive, aerospace, hand tools and electronic industries thanks to their light weight, high specific strength, adequate corrosion resistance and good castability. Al and Zn are the primary alloying elements in commercial Mg alloys and commonly used in automotive industries. READ MORE

  4. 2. Post-treatment of Alloy 718 produced by electron beam melting

    Author : Sneha Goel; Shrikant V. Joshi; Uta Klement; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Electron Beam Melting; Alloy 718; HIP; Heat Treatment; Solutionizing; Aging; HIP HT; Microstructure; γ ; δ; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Electron beam melting (EBM), a metal additive manufacturing (AM) process, has received considerable industrial attention for near net shape manufacture of complex geometries with traditionally difficult-to-machine materials. This has fuelled considerable academic interest in investigating EBM of Alloy 718, a nickel ironbased superalloy possessing an exciting combination of good mechanical behaviour and cost effectiveness.

    Abstract : Additive manufacturing (AM) has emerged as a disruptive technology and it is a vital part in the present era of fourth industrial revolution, Industry 4.0. READ MORE

  6. 4. SmCo for polymer bonded magnets : Corrosion, silanization, rheological, mechanical and magnetic properties

    Author : Muhammad Irfan Qadeer; Steven Savage; Mikael Hedenqvist; Uta Klement; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organofunctional alkoxysilanes; High temperature oxidation; Rare-earth magnetic alloys; SmCo; Isothermal; Non-isothermal; Microstructure; Magnetic properties;

    Abstract : This thesis presents the study of organofunctional alkoxysilane coatings to prevent high temperature oxidation of Sm-Co powders. Sm-Co are important permanent magnetic alloys, owing to their high Curie temperature and large values of magnetocrystalline anisotropy. READ MORE

  7. 5. Enhanced heat transfer and tool wear in high-pressure coolant assisted turning of alloy 718

    Author : Nageswaran Tamil Alagan; Tomas Beno; Uta Klement; Anders Wretland; Mikael Olsson; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Cavitation; Coolant-boiling; High-pressure coolant; Heat dissipation; Leidenfrost effect; Textured insert; Tungsten carbide; Tool life; Tool wear; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Heat generated in a machining process is a common and critical obstacle faced in today's manufacturing industries. The heat generated in the cutting zone has adirect negative influence on the tool life, which, in turn contributes to increasing the manufacturing costs. READ MORE
