  1. 36. Evolution of artificial defects during shape rolling

    Författare :Mirjana Filipovic; Stefan Jonsson; Per-Olov Perä; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape rolling; wire rod rolling; artificial defects; defect evolution; surface cracks; porosity; FEM; high speed steel; stainless steel; Other materials science; Övrig teknisk materialvetenskap; Initiering och utveckling av defekter under spårvalsning;

    Sammanfattning : Very often defects are present in rolled products. For wire rods, defects are very deleterious since the wire rods are generally used directly in various applications. For this reason, the market nowadays requires wire rods to be completely defect-free. Any wire with defects must be rejected as scrap which is very costly for the production mill. LÄS MER

  3. 37. Att göra hem – En studie av unga mäns boende och konsumtion på 2000-talet

    Författare :Maria Fuentes; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; home; consumption; relational place; affordance; connectivity; craft consumption; housing pathways; property commodity; porosity; identity; male homemakers;

    Sammanfattning : “Home” has become a commercialised place in contemporary Sweden. As both cause and ef- fect of this development, the Swedish market for furniture and interior decoration has grown significantly during the last twenty years. LÄS MER

  5. 39. Deformation and Fatigue Behaviour of Porous and Dense Austenitic Stainless Steel

    Författare :Ulf Lindstedt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical properties; austenitic stainless steel; PM steel; nitrogen; small cracks; previous particle boundaries; microplasticity; grain size dependence; fatigue; porosity;

    Sammanfattning : PM stainless steels are increasing in use and are expected to do so in the future. A lot of work has been carried out concerning production and sintering of stainless steel powders and on the resulting corrosion behaviour. The deformation behaviour of these materials is less studied. LÄS MER

  7. 40. Mass Transport in Apple Tissue: Effects of Tissue Structure and Osmotic Processing Conditions

    Författare :Nikolaos Mavroudis; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; drying; porosity; shrinkage; cell vitality; apple structure; apple; osmotic processing; mass transport; mass transport mechanisms;

    Sammanfattning : Osmotic processing can be a very useful processing step in today’s food industry enabling the production of high quality natural food ingredients out of plant tissues. The maintenance of high product quality is quite product specific with regard to quality attributes. These attributes include fresh/like appearance, taste, texture and composition. LÄS MER
