1. 21. Microstructure Modelling of Additive Manufacturing of Alloy 718

   Författare :Chamara Kumara; Per Nylén; Johan Moverare; Lars-Erik Lindgren; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-Field Modelling; Additive Manufacturing; Phase Transformation; Solidification; Heat Treatment; Superalloy; Production Technology; Produktionsteknik;

   Sammanfattning : In recent years, additive manufacturing (AM) of Alloy 718 has received increasing interest in the field of manufacturing engineering because of its attractive features compared with those of conventional manufacturing methods. Nevertheless, owing to the inherent nature of the process, the build material is exposed to complex thermal conditions that affect the microstructure. LÄS MER

3. 22. Crystallization in additive manufacturing of metallic glass

   Författare :Anders Ericsson; Hållfasthetslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amorphous metals; Crystallization; Laser powder bed fusion; Neutron scattering; Phase-field theory; Classical nucleation theory;

   Sammanfattning : Metallic glasses are non-crystalline metals that are obtained by rapid cooling of the melt to bypass crystallization. The amorphous atomic structure shows enhanced properties relative to the crystalline counterpart. For example, enhanced mechanical properties, improved corrosion resistance, as well as excellent soft magnetic properties. LÄS MER

4. 23. Design of flexible lattice structures : a design for additive manufacturing perspective

   Författare :Satabdee Dash; Innovation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design for additive manufacturing; DfAM; Lattice structures; Flexibility; Compuational methods; Numerical modelling; Engineering design process;

   Sammanfattning : Recent years has seen an unprecedented growth in emerging technologies like Additive manufacturing (AM), augmenting the manufacturing capabilities through a multitude of opportunities while also introducing unique constraints, such as support structures, and post-processing requirements. Taking full advantage of the potential of AM demands product designs to be optimised for both opportunities and constraints specific to AM, requiring evolution from the traditional design for manufacturing to design for additive manufacturing (DfAM).

5. 24. Assessment of waters with complex contamination : Effect-based methods for evaluating wastewater treatment requirements and efficiency

   Författare :Veronica Ribé; Åke Forsberg; Monica Odlare; Emma Nehrenheim; Rune Berglind; Magnus Breitholtz; Mälardalens högskola; []
   Nyckelord :Effect-based test methods; wastewater treatment; ecotoxicology; bioassays; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : The access to clean water is one of the prerequisites for a modern, industrialized society. The amount of water withdrawn for human activities has risen exponentially during the last 100 years. This rise in water use is accompanied by the production of vast quantities of contaminated water.
