  1. 252. Effect of rare earth substitution on the structural, electrical and magnetic properties on the piezoelectric A1-xSrxTiO3 system (TUE-PO1-615-01)
    Dr Adolfo Quiroz (Universidad Tecnológica de Xicotepec de Juárez)

    Poster

    Ceramic powders A1-xSrxTiO3 (where x = 0.02, and A=Ba2+, Pr3+, Sm3+, Eu3+, and Er3+) were synthesized by solid-state reaction method and sintered at up to 1400 °C. The phase formation, elemental composition, and microstructure of the sintered samples were investigated by TGA, XRD, EDX and SEM techniques, respectively. The results of the partial substitution of Ba ions by other rare earth ions...

  2. 327. Evaluation of mass production results of cryogenic structural stainless steels for ITER toroidal field coil (TUE-PO1-615-02)
    Mr Takeru Sakurai (QST)

    Poster

    High tensile strength and fracture toughness at 4 K are required on structural materials for ITER Toroidal Field Coil (TFC) cases to withstand huge electromagnetic forces generated on TFC. However, hence there were no standard materials satisfying ITER requirements, QST developed new cryogenic structural material of JJ1 (0.03C-12Cr-12Ni-10Mn-5Mo-0.24N), and optimized nitrogen contents of 316LN...

  3. 302. Research on Nondestructive Examination of Jacket Sections for CFETR TF Coil (TUE-PO1-615-03)
    Dr XIAOCHUAN LIU
    16/11/2021, 13:15
    Poster

    The Chinese Fusion Engineering Testing Reactor (CFETR) is aiming to bridge the gap between the ITER and the first commercial fusion power plant, a necessary complement of the ITER. The requirement for sustaining long burn duration as specified in the duty time CFETR mission necessitates the use of
    superconducting magnets. Totally 16 TF D-shaped (six arcs and a straight leg) coils which are...

  4. 239. Silver nanowires - copper composite wires for non-destructive pulsed fields : importance of avoiding the formation of a silver/copper alloy relative to the electrical resistivity and the tensile strength (TUE-PO1-615-04)
    Simon TARDIEU (Laboratoire National des Champs Magnétiques Intenses, EMFL, CNRS-INSA-UGA-UPS)
    16/11/2021, 13:15
    Poster

    A commercial micrometric Cu powder is mixed with Ag nanowires (diameter 0.2 µm, length 30 µm) synthesized in-house, in order to prepare a powder with a Ag content of 1 vol. %. Two powder batches are prepared for consolidation into cylinders (diameter 8 mm, length 33 mm) by spark plasma sintering.

    One cylinder is sintered at 400 °C, where the solubility of Ag in Cu is below 0.1 vol. %, which...

  5. 925. Thermal resistance between metallic surfaces of copper and stainless steel at different temperatures and contact pressures for high current HTS Cable-in-Conduit Conductors (TUE-PO1-615-05)
    Dr Nadezda Bagrets (Karlsruhe Institute of Technology)
    16/11/2021, 13:15
    Poster

    High Temperature Superconductors (HTS) is a promising option for high current Cable-In-Conduit Conductors (CICC) for large high-field magnets. CICC are often constructed from several HTS strands which themselves are formed from individual HTS tapes. Quench propagation is CICCs is currently under intensive investigation, and it can be predicted by modelling the entire structure. However, for...
