  • 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...

  • Computer simulation of phase transitions in zirconia

    Creator:
    Love, Michael J.
    Abstract:
    Experimental data on the structural phase changes in zirconia are summarized. The computational techniques of molecular dynamics are reviewed and equations of motion are formulated which allow the study of phase changes as a function of temperature and pressure. The molecular dynamics program NPT which was written for this purpose...
