4. 23. Post-treatment of Alloy 718 produced by electron beam melting

   Författare :Sneha Goel; Shrikant V. Joshi; Uta Klement; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Electron Beam Melting; Alloy 718; HIP; Heat Treatment; Solutionizing; Aging; HIP HT; Microstructure; γ ; δ; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Electron beam melting (EBM), a metal additive manufacturing (AM) process, has received considerable industrial attention for near net shape manufacture of complex geometries with traditionally difficult-to-machine materials. This has fuelled considerable academic interest in investigating EBM of Alloy 718, a nickel ironbased superalloy possessing an exciting combination of good mechanical behaviour and cost effectiveness.

5. 24. On restart of automated manufacturing systems

   Författare :Patrik Bergagård; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supervisory control theory; Error recovery; Manufacturing systems; Restart; Extended finite automata; Discrete event systems;

   Sammanfattning : Highly automated manufacturing systems have gained industrial popularity for their ability to combine high product volumes with high product quality. The high cost of investment in combination with many linked manufacturing systems in a factory, requires that the production runs smoothly with high utilization of the resources and that stoppages are avoided.

7. 25. Computational weld mechanics : Towards simplified and cost effective FE simulations

   Författare :Ayjwat Awais Bhatti; Zuheir Barsoum; Lennart Josefson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : It is the demand of the world’s ever increasing energy crisis to reduce fuel consumption wherever possible. One way of meeting this demand is by reducing the weight of a structure by replacing thick plates of low strength steel with thin plates of high strength steel in the structure. LÄS MER
