Sažetak
Titanium alloys of beta -type have become a very important class of biomaterials because of their unique combination of high strength, low Young’ s modulus, good corrosion resistance and excellent biocompatibility. In this work a new ternary titanium alloys, composed of non-toxic and non-allergic elements like chromium and cobalt, have been designed in order to achieve beta -phase structure. Samples of four Ti-10Co-xCr alloys with chromium content 10-25 at.% were prepared by vacuum arc melting technique. They were analyzed by scanning electron microscope, X-ray diffraction and compression tests. The experimental results show that all alloys have two-phases microstructure, with a small portion of third phase. The beta -phase with bcc type of crystal structure is dominated and the intermetallic compound Ti2Co precipitated on the grain boundaries. All alloys exhibited high compressive strength of 1391-1958 MPa, high yield strength 1290-1540 MPa and Young’ s modulus in the range of 30-59 GPa, together with the large plastic strains. The present results indicate that the combination of high strength and low elastic modulus of Ti-Co-Cr alloys offer potential advantages in a biomedical applications.
