Abstract

Titanium alloys are characterized by great versatility arising from the ability to obtain a wide spectrum of properties by controlling the alloying elements and thermo-mechanical treatments that determine the microstructure. The determining factors for the workability of titanium alloys are related to the structure of the alpha phase (HCP) and the strong dependence of the alpha and beta phases on processing variables such as temperature, strain and strain rate. Therefore, proper selection and control of these parameters in each deformation step is critical to obtain an optimum combination of mechanical properties and microstructure of the final product. The tested material is titanium commercially pure (Ti CP (Ti Gr4)), which despite being an alpha alloy, it is seen that small amounts of iron can change the microstructural evolution of the alloy.
