  3. 2. Modeling of Precipitation by Structural Phase-Field Crystal Method

    University essay from Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Author : Jacob Holmberg-Kasa; [2021]
    Keywords : strain-age cracking; SAC; structural phase-field crystal; XPFC; nickel-based alloys; precipitation;

    Abstract : Nickel-based alloys are used in components such gas turbines within the aerospace industry and electric power generation due to its high tensile, rapture and creep strength. Increasing the efficiency of gas turbines are crucial to reduce emissions within the aerospace industry and increasing power gain for electric power generation. READ MORE

  4. 3. Investigation of Ductility Dip at 1000˚C in Alloy 617

    University essay from KTH/Materialvetenskap

    Author : Julia Sjöström; Helena Åkesson; [2017]
    Keywords : Ductility dip cracking; Ni-based alloy; tortuous grain boundaries; intergranular precipitates; grain boundary migration; superalloy; M23C6; Ti N; C ; solid state cracking; dynamic recrystallization;

    Abstract : Alloy 617 displays a ductility dip during straining at exactly 1000˚C, leading to brittle fracture. A sudden decrease in ductility appearing during Gleeble hot ductility tests of Ni-based superalloys is a well-known phenomenon, while its cause is unknown. READ MORE
