Abstract
The paper presents the effects of some alloying elements (Al, Fe, and Mn) on the microstructure and microhardness of titanium alloys that can be used for medical applications. The experimental alloys were produced by melting in an argon inert atmosphere of the RAV furnace, using high-purity chemical elements and the commercial alloy Ti8Al4V. Under the same conditions, other binary alloys (Ti9Al, Ti5Fe, Ti3Mn, and Ti6Mn) were developed for highlighting the effects of the singular elements Al, Fe and Mn on the characteristics of titanium alloys. Microstructural analysis revealed the changes of microstructure produced by the introducing of alpha stabilizing elements (Al) or beta stabilizers (Fe, Mn). We then analyzed the effects of each type of chemical on the metal matrix microhardness and the density of the experimental alloys.
