  • 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...

  • Bioactive glass filled resin composites : mechanical properties and resistance to secondary tooth decay

    Creator:
    Khvostenko, Dmytro
    Abstract:
    Dental resin composites are widely used in modern dentistry due to their aesthetic appearance. However, resin based restorations have inferior mechanical properties (fracture is the second reason for restorations replacement) in comparison to alloy based composites and their antimicrobial properties still remain poor, leading to secondary tooth decay development on...

  • Refractory Amorphous Metal Thin Films

    Creator:
    Olsen, Kristopher R.
    Abstract:
    Amorphous metal thin films lack the grain boundaries and dislocations present in crystalline metal films. As a result, amorphous metal films can be more mechanically robust, atomically smooth, and more resistant to chemical attack than crystalline metals. However, amorphous metals are meta-stable and subject to crystallization upon heating, thus limiting...
