Research

Planar Flow Casting of Amorphous Metals
This examination focuses on the achievement of amorphous and nanocrystalline Cu, Ni, Al and Fe alloys utilizing planar flow casting. The detailed consideration of the amorphous to crystalline transformation and its effect on the physical/mechanical properties of these materials is also under investigation. Future studies will incorporate reactive amorphous metal alloys, e.g., Mg, Ti and Zr base systems.

Severe-Plastic Deformation of Advanced Metallics and Composites
This examination considers the influence of severe plastic deformation in single and two phase systems. Particular focus on achieving an understanding of grain boundary structure in bulk nano/ultra-fine grained titanium alloys and composites and the influence of this structure on surface reactivity, high cycle fatigue and wear performance.

Adaptive Manufacturing of Smart Materials
This examination combines the attributes of amorphous/nanograined metallic materials, ceramics and polymer composites to form bulk components utilizing ultrasonic consolidation. Includes definition of the effect of ultrasonic energy on localized deformation and phase stability in metallic, ceramic/metallic and ceramic/polymeric composites.

Synthesis of Low Modulus, Wear Resistant Biocompatible Orthopedic Alloys
This examination focuses on first prinbcipal synthesis of low modulus, wear resiustant titanium alloys for orthopedic application. It is being conducted in cooperation with a multi-disciplinary group examining the influence of alloy chemistry, processing and surface treatment on control and optimiization of this new class of alloys.

Phase Transformations in Titanium Alloys
This examination considers martensitic and diffusional transformations in titanium alloys. It includes consideration of composition, microstructure particularly at the nano-scale and crystallography (texture) on aging response of metastable beta titanium alloys, transition temperatures in titanium shape memory alloys and the effect of cooling/heating rate on martenisteic/diffusion controlled transformations in titanium alloys.
