   Författare :Cheng-Han Yu; Johan Moverare; Ru Lin Peng; Christian Leinenbach; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser powder bed fusion; Slow strain rate tensile testing; Short-term creep; Low cycle fatigue; Neutrons; Anisotropy; Crystallographic texture; Microstruc-ture; Dislocation structure; Lasersmältning i pulverbädd; Provning med långsam töjningshastighet; korttidskryp; Lågcykelutmattning; Neutroner; Anisotropi; Kristallografisk textur; Mikrostruktur; Dislokationsstruktur;

   Sammanfattning : Additive manufacturing (AM), also known as 3D printing, is a general concept of building a three-dimensional object layer-by-layer. AM breaks through the manufacturing limitations in conventionally subtractive manufacturing, leading to a great design freedom of components with complex geometries. LÄS MER

3. 2. Anisotropic mechanical behaviors and microstructural evolution of thin-walled additively manufactured metals

   Författare :Cheng-Han Yu; Johan Moverare; Ru Lin Peng; Joe Kelleher; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hot tensile testing; slow strain rate tensile testing; creep; anisotropy; crystallographic texture evolution; deformation twinning; Varmdragprov; Dragprov med låg töjningshastighet; kryp; anisotropi; kristallografisk textur; deformationstvillingar;

   Sammanfattning : Additive manufacturing (AM), also known as 3D printing, is a concept and method of a manufacturing process that builds a three-dimensional object layer-by-layer. Opposite to the conventional subtractive manufacturing, it conquers various limitations on component design freedom and raises interest in various fields, including aerospace, automotive and medical applications.

4. 3. Process-microstructure-corrosion interrelations for stainless steel

   Författare :David Lindell; Rachel Pettersson; Rebecca L. Higginson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; processing; annealing; pickling; microstructure; corrosion; anisotropy; oxyfuel; Kemi; Chemistry;

   Sammanfattning : Stainless steels were first developed in the early 20th century and have since then emerged as a very diverse class of engineering materials. Along with steels having new combinations of properties, there is a continuous development of new technologies allowing the material to be produced in a faster and more energy effcient manner.

5. 4. Characterisation of Functional Pressing Die Surfaces

   Författare :Johan C Berglund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional correlation; functional surface; functional filtration; pressing die; multi-scale analysis; characterisation; finish milling; texture anisotropy; polishing; surface topography;

   Sammanfattning : The manufacture of dies and moulds is a critical aspect of many production systems since the manufacturing and try-out of new dies and moulds often is essential in determining the lead-time and quality of a new production system. In the automotive industry, many new car models are introduced each year and for each of these models, a new set of pressing dies has to be designed and manufactured. LÄS MER

7. 5. Effects of composition and the production process on formability of austenitic stainless steels

   Författare :Roger Andersson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

   Sammanfattning : Formability of austenitic stainless steels is strongly influenced by the chemical composition, the internal texture and the deformation conditions. The purpose of this study is to determine how small variations in chemical composition and minor variations in the production process are influencing the formability of type 304 and 316 austenitic stainless steels.
