  1. 1. Microstructural and Micro-Mechanical Characterization of As-built and Heat-treated samples of HASTELLOY X produced by Laser Powder Bed Fusion Process

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Onimisi Sanni; [2022]
    Keywords : As-built Hastelloy X blocks; Laser powder bed fusion LPBF ; Solution heat-treatment; Disrupted epitaxial growth; Melt Pool Boundaries MPB ; Grain Boundaries GB ; Precipitates; In-situ microtensile testing; microhardness; Mechanical properties; Twin grain boundary fractions;

    Abstract : Microstructure and micro-mechanical characterization of as-built and heat-treated samples of Hastelloy X produced by laser powder bed fusion (LPBF) process has been carried out in this study. As-built LPBF blocks were solution heat-treated at 1177°C and 1220°C followed by fast cooling. READ MORE

  3. 2. Independent Project in Chemical Engineering and Materials Engineering : A literature study of powder-based additive manufacturing

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Daniel Feldt; Petra Hedberg; Asker Jarlöv; Elsa Persson; Mikael Svensson; Filippa Vennberg; Therese You; [2018]
    Keywords : Additive manufacturing; selective laser melting; electron beam melting; binder jetting; stainless steel; tool steel; nickel alloys;

    Abstract : The focus of this literary study was additive manufacturing (AM) and the purpose was to find general trends for selected materials that have been additively manufactured and compare them to results from other reviews. The raw materials studied were stainless steels 316L, 17-4 PH, 15-5 PH and 420, as well as tool steel H13 and nickel alloys 625, 718 and Hastelloy X. READ MORE

  5. 4. A study of micro- and surface structures of additive manufactured selective laser melted nickel based superalloys

    University essay from KTH/Materialvetenskap

    Author : Emil Strand; Alexander Wärnheim; [2016]
    Keywords : additive manufacturing; selective laser melting; microstructure; surface roughness; superalloy;

    Abstract : This study examined the micro- and surface structures of objects manufactured by selective laser melting (SLM). The results show that the surface roughness in additively manufactured objects is strongly dependent on the geometry of the built part whereas the microstructure is largely unaffected. READ MORE

  6. 5. Weld Analysis in Combustion Chambers Subjected to Thermo-Mechanical Fatigue Load Conditions

    University essay from Hållfasthetslära

    Author : Johnny Johansson; [2011]
    Keywords : Weld; analysis; TMF; fatigue;

    Abstract : At cyclic operation of gas turbines, components are subjected to thermo-mechanical fatigue (TMF) due to the high temperature gradients that arises. In this thesis life assessment of welds in combustion chambers are at focus. READ MORE
