Research project: Processing of nanostructured titanium for use in medical implants - Dormant - Dormant

Currently Active: 

Commercial purity (CP) titanium alloys such as Ti-6% Al-4% V are in wide use for medical implants from hip and knee replacements to dental implants for crowns and orthodontal purposes.  These materials are effective but the applications are limited by the overall strength of the alloy.  An increase in strength would permit the use of smaller parts and less invasive surgery.

The strength of Ti may be increased by reducing the grain size, for example through processing the metal using equal-channel angular pressing (ECAP) where it is pressed through a channel bent through an angle of 90 degrees. 

The results from preliminary studies show that we are able to process nanostructured CP titanium.  We plan now to examine the technology required for the successful processing of titanium for use in commercial biomedical applications.
