Abstract

Many types of alloys are available as dental implants, but titanium and its alloys have been widely 
used due to their outstanding properties. In this research titanium alloys with different Zr contents 
were prepared by arc-melting. Phase identification was performed by XRD analysis. Microstructure 
was observed by light microscope after etching in two solutions. Detailed microstructural 
observations were realized by SEM and EDS. Vickers hardness measurements were performed as 
well. Alloy with higher Zr content shows nearly beta-phase structure and more adequate hardness
values for dental implants than alloy with lower Zr content.
