2. Electrochemical corrosion analysis of nickel-based superalloys
Master-uppsats, KTH/Yt- och korrosionsvetenskapSammanfattning : 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. LÄS MER
3. 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/MaterialvetenskapSammanfattning : 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
4. Investigations of Large Size Non-Metallic Inclusions in the Nickel-based alloy Inconel 718
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : 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. LÄS MER
5. Characterisation of additively manufactured Inconel 718 alloy by using electrolytic extraction
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : 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). LÄS MER
