  5. 8. Directed Energy Deposition Additive Manufacturing and Welding of Duplex Stainless Steel using Laser Beam

    Author : Amir Baghdadchi; Leif Karlsson; Joel Andersson; Vahid Hosseini; Dirk Engelberg; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Duplex stainless steel; Laser welding; Additive manufacturing; Direct Energy Deposition using a Laser Beam; Microstructure characterization; Duplexa rostfria stål; Lasersvetsning; Additiv tillverkning; Metalldeponering med laser; Mikrostruktur; Production Technology; Produktionsteknik;

    Abstract : Duplex stainless steels (DSSs), with a ferritic-austenitic microstructure, are used in a wide range of applications thanks to their high corrosion resistance and good mechanical properties. However, efficient and successful production and joining of DSS require precise control of processes and an in-depth understanding of the relations between composition, processing thermal cycles, resulting microstructures and properties.

  6. 9. Phase separation in duplex stainless steel: characterization and mitigation

    Author : Jianling Liu; Peter Hedström; Joakim Odqvist; Wangzhong Mu; Aniruddha Biswas; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duplex stainless steel; 475 °C embrittlement; phase separation; small-angle neutron scattering; mechanical properties; alloying elements; cooling rate; magnetic field; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : Duplex stainless steel (DSS) is a category of widely used stainlesssteel, which are strategically important in a variety of applications such asin the food industry, chemical engineering plants and nuclear power plants,due to their attractive combination of mechanical properties and corrosionresistance. However, these steel grades are sensitive to the so-called ‘475°Cembrittlement’, because of a phase separation (PS) phenomenon in theferrite phase, which decomposes into Fe-rich ferrite (α) and Cr-rich ferrite(α'), when exposed to temperatures within the miscibility gap.

  7. 10. Medical decision support systems based on the Arden Syntax in the clinical laboratory

    Author : Bo Johansson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Decision Support Systems (DSSs) are computer systems that permit explicit representation of knowledge and can execute a computer program that uses the knowledge to assist in the decision process. A clinical DSS uses both clinical data and medical knowledge to help health professionals make clinical decisions. READ MORE
