  • Microstructural banding in thermally and mechanically processed titanium 6242

    Creator:
    Kansal, Utkarsh
    Abstract:
    Ti-6Al-2Sn-4Zr-2Mo-0.1Si specimens were shaped by repeated cycles of heating (to 954 °C) and hammer or press forging followed by a solution anneal that varied from 968 to 998 °C. The coupons were originally extracted from billets forged below the beta trans us ( 1009 °C) and slow cooled to ambient...

  • Rheological measurements of bulk metallic glass forming alloys above the liquidus temperature

    Creator:
    Shaw, Tyler A.
    Abstract:
    A high temperature high vacuum rheometer has been designed, fabricated, and tested for the study of the steady shear viscosity for multicomponent bulk metallic glass forming alloys. This rheometer has an operating range up to 1525 K, rotational frequencies of 9.4*10⁻³-3.7*10¹ radians/s, and a calibrated viscosity range of 9.6*10⁻³ and...

  • Mechanical properties of Nb-Ti composite superconducting wires

    Creator:
    Liu, He
    Abstract:
    Mechanical properties of Nb-Ti composite superconducting wires were tested at room temperature. The results were analysed using simple composite theory, the rule of mixtures. The objective is to predict the mechanical properties of Nb-Ti superconducting composite wires as a function of volume ratio and geometry of the components, the composite...
