                         biomedical applications due to their high strength, corrosion 
                         resistance and elastic modulus. However, these materials have 
                         recently been shown to exhibit ion release and poor physiological 
                         integration that may result in fibrous encapsulation and further 
                         biomaterial rejection. In order to be a successful replacement for 
                         bone current approaches for enhancing the mechanical and

                         provides greatly improved mechanical properties which include 
                         fracture toughness and workability. Studies have shown techniques
