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.
