Effect of composition on the structure and properties of Ti-Co-Cr alloys

The present work is a study of six as-cast Ti- Co-Cr alloys in the Ti-rich region with the purpose of examining the possibility of obtaining a new beta-type alloys. Two experimental alloys Ti80-Co10-Cr10 and Ti70- Co10-Cr20 are nearly single phases and are identified as bcc beta-Ti phase. They also diplay the lowest hardness values and the best corrosion properties. The present study indicates that the region of biomedically- acceptable ternary Ti-rich alloys is situated within lower concentrations of alloying elements , i.e. about 10 at.% Co and 20 at.% Cr.
