  1. 1. Investigation of Non-Metallic Inclusions in Inconel 718 by Using Conventional Cross-Sectioned (CS) Method and Experimental Extraction Metal-Surfaced (MS) Method

    Master-uppsats, KTH/Materialvetenskap

    Författare :Mehreen Baig; [2022]
    Nyckelord :;

    Sammanfattning : Inconel 718 is a nickel-based alloy, predominantly used in the oil and gas industry, in aircraft engines as well as in gas turbine engines. It provides exceptional properties like high strength, creep resistance, corrosion resistance and long fatigue life at high temperatures as well as in cryogenic environments. LÄS MER

  3. 2. Process Optimization and Characterization of Inconel 718 Manufactured by Metal Binder Jetting

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Tobias Eriksson; [2021]
    Nyckelord :Inconel718; Additive Manufacturing; Binder Jetting; Powder Metallurgi; Superalloy;

    Sammanfattning : The development of a process chain for Inconel 718 production utilizing Binder Jetting has been investigated. Different powder sources were compared by the effect they had on machine compatibility, powder bed packing, recyclability, green density, sintering parameters, final density, porosity, and mechanical properties.

  4. 3. Utvärdering av osäkerhet i sprickfortplantningsmodeller

    Magister-uppsats, Högskolan Väst/Avd för tillverkningsprocesser

    Författare :Gabriel Tuyishimire; [2015]
    Nyckelord :Crack growth rate; Threshold; NASGRO; Inconel718; Ti6-4; Potential Drop; load ratio; crack closure; fatigue;

    Sammanfattning : In aerospace industry and other major mechanical industry systems, engineering components that are subjected to cyclic loads often lead to progressive crack growth that eventually results in struc-tural fracture. The damage tolerance design which is based on the assumption of pre-existed flaws in a structure is an important approach in aircraft industry since it is impossible to have flaw-free manufactured components.

  5. 4. High temperature fatigue crack propagation in Inconel718

    Master-uppsats, Hållfasthetslära; Tekniska högskolan

    Författare :Babak Sharifimajd; [2010]
    Nyckelord :;

    Sammanfattning : In this work, three different series of fatigue experiments on INCONEL718 will be discussed. For each type of fatigue experiment, the method of evaluation the raw data obtained at the matrial laboratory will be mentioned. Morover, from the obtained results, the fatigue properties of INCONEL718 will be presented in detail. LÄS MER
