  1. 1. Additive Manufacturing using Alloy 718 Powder Influence of Laser Metal Deposition Process Parameters on Microstructural Characteristics

    University dissertation from Trollhättan : University West

    Author : Andreas Segerstark; Högskolan Väst.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Laser metal deposition; powder; superalloy; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Additive manufacturing (AM) is a general name used for production methodswhich have the capabilities of producing components directly from 3D computeraided design (CAD) data by adding material layer-by-layer until a final component is achieved. Included here are powder bed technologies, laminated object manufacturing and deposition technologies. READ MORE

  4. 4. Microstructure model for Ti-6Al-4V used in simulation of additive manufacturing

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Corinne Charles Murgau; Corinne Charles; Högskolan Väst.; Luleå tekniska universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik; Titanium alloy; Ti-6Al-4V; Welding; Metal deposition; Additive manufacturing; Wire feed; Finite Element Method; Microstructure model; Johnson-Mehl-Avrami- Kolmogorov; Thermally driven; Material Mechanics; Materialmekanik;

    Abstract : This thesis is devoted to microstructure modelling of Ti-6Al-4V. The microstructure and the mechanical properties of titanium alloys are highly dependent on the temperature history experienced by the material. The developed microstructure model accounts for thermaldriving forces and is applicable for general temperature histories. READ MORE

  5. 5. Qualification of Metal Additive Manufacturing in Space Industry Challenges for Product Development

    University dissertation from Luleå : Luleå University of Technology

    Author : Christo Dordlofva; Luleå tekniska universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Space industry; Product Development; Qualification; Design for Additive Manufacturing;

    Abstract : Additive manufacturing (AM), or 3D printing, is a collection of production processes that has received a good deal of attention in recent years from different industries. Features such as mass production of customised products, design freedom, part consolidation and cost efficient low volume production drive the development of, and the interest in, these technologies.
