  3. 2. Electrochemical corrosion analysis of nickel-based superalloys

    University essay from KTH/Yt- och korrosionsvetenskap

    Author : Robin Gonzalez; [2022]
    Keywords : Electrochemistry; corrosion; nickel; polarization; EIS; Elektrokemi; korrosion; nickel; polarisation; EIS;

    Abstract : Elektrokemisk korrosionsanalys av legeringar är en essentiell del av den större materialanalysen som måste utföras när en legerings lämplighet för en viss applikation evalueras. Nickelbaserade legeringar är kända för sin utmärkta korrosionsresistans, och de Ni-Cr-Mo-baserade legeringarna 59, 625, och 718 är också så kallade superlegeringar. READ MORE

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

    University essay from KTH/Materialvetenskap

    Author : Mehreen Baig; [2022]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 4. Investigations of Large Size Non-Metallic Inclusions in the Nickel-based alloy Inconel 718

    University essay from KTH/Materialvetenskap

    Author : Yuehui Ma; Wardah Saleem; [2022]
    Keywords : ;

    Abstract : Inclusions of different types are present in all steels. How dangerous these are for the properties of the material depends on their chemical composition and the manufacturing process. READ MORE

  6. 5. Characterisation of additively manufactured Inconel 718 alloy by using electrolytic extraction

    University essay from KTH/Materialvetenskap

    Author : Leyla Koort; Viktoria Sutorius Trollbäck; [2021]
    Keywords : ;

    Abstract : The formation of non-metallic inclusions (NMIs) are common in all steel grades and it is not possible  as  of  today  to  be able  to  remove  all  of them.  The  inclusions  are  categorised  into endogenous (oxides, nitrides, sulfides, carbides, and phosphides), and exogenous (entrapment of  nonmetals:  slag, mold).
