  1. 1. Företagsledning i strategiskt vakuum : om aktörer och förändringsprocesser

    Författare :Gunnar Åkesson; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Ofta hävdas nödvändigheten av en strategi när man framgångsrikt skall driva en verksamhet. Ibland förekommer dock fall där ett företags omgivning blivit så komplex och så föränderlig att det är mycket svårt att formulera trovärdiga strategier. LÄS MER

  3. 2. Electron beam powder bed fusion of Nitinol : A development from production process window towards delicate structures

    Författare :Lin Zeyu; Amir Rashid; Carolin Körner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production Engineering; Industriell produktion;

    Sammanfattning : Electron beam powder bed fusion (PBF-EB) is increasingly attracting attention for manufacturing the near-net shape parts due to its incomparable merits, such as free residual stress and superior mechanical performance. Nickel Titanium (NiTi) as the most widely used functional alloy, has not been systematically explored for manufacturing using PBF-EB despite the perfect vacuum and high temperature manufacturing environment.
