  1. 1. EB-PBF additive manufacturing of Alloy 718 : Effect of shot peening on surface characteristics and high temperature corrosion performance

    University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Author : Venkataramanan Mohandass; [2019]
    Keywords : Alloy 718; additive manufacturing; electron beam-powder bed fusion; surface engineering; shot peening; high temperature corrosion;

    Abstract : There is an upsurge of research interest on Alloy 718 additively manufactured (AM) by electron beam powder bed fusion (EB-PBF) technique in aero and land-based gas turbine engines. However, the surface quality of the manufactured components has always been a major challenge. READ MORE

  2. 2. Reduction of Set-recovery of Surface densified Scots Pine by Furfuryl Alcohol

    University essay from Luleå tekniska universitet/Träteknik

    Author : Lei Han; [2019]
    Keywords : surface densification; set-recovery; hardness; furfuryl alcohol;

    Abstract :  For wood products such as flooring and worktop, only one surface is normally exposed in their use, and the mechanical properties like hardness and wearing resistance of that surface is then important. Since mechanical properties are strongly related to the density, surface densification, i.e. READ MORE

  3. 3. From Bloomery Furnace to Blast Furnace : Archeometallurgical Analysis of Medieval Iron Objects From Sigtuna and Lapphyttan, Sverige

    University essay from KTH/Materialvetenskap; KTH/Materialvetenskap

    Author : Andreas Helén; Andreas Pettersson; [2019]
    Keywords : ;

    Abstract : During the Early Middle Ages, the iron production in Sweden depended on the bloomery furnace, which up to that point was well established as the only way to produce iron. Around the Late Middle Ages, the blast furnace was introduced in Sweden. READ MORE

  4. 4. 'The battle never stops' - A discourse analysis of Nerf toy gun advertisements

    University essay from Malmö universitet/Kultur och samhälle

    Author : Léa-Noémi Huber; [2019]
    Keywords : Toy guns; Nerf; Discourse analysis; Militarisation; Masculinity;

    Abstract : This study consists of a discourse analysis of five Nerf toy gun commercials which were aired on US television between 2017 and 2018 and were produced by the international toy gun company Hasbro Inc. Using Gillian Rose’s model of discourse analysis I as a method in combination with discourse theory, theoretical concepts of militarisation and masculinity, the question how militarised masculinity is produced through the discourse of the selected Nerf toy gun commercials has been posed and guided the analysis of this study.

  5. 5. Characterization of Heat Treated LMwD Ti-6Al-4V to Study the Effect of Cooling Rate on Microstructure and Mechanical Properties

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Emil Edin; [2019]
    Keywords : Ti-6Al-4V; LMwD; Characterization; Alpha Laths;

    Abstract : In this work, the influence of different cooling rates (5, 20, 50 and 100 °C/s) on the microstructure and mechanical properties of Laser Metal Wire Deposited (LMwD) Ti-6Al-4V was investigated, this was done using a thermal-mechanical physical simulation system (Gleeble 3800, DSI). Two different soak times above β transus (held at 1100 °C), 5 and 40 s, were used and after cooling to 150 °C, the samples were tensile tested. READ MORE
