| Popis: | In the paper are presented the experimental researches made in order to obtain a new titanium alloy - Ti15Mo5W used for medical applications with improved mechanical characteristics and modulus of elasticity. In this regard Ti15Mo with addition of W alloy was designed with the intention of obtaining b-Ti phase stability. For this, we studied the influence of: the bond order, energy level of metal d-orbital, ratio of valence electrons/atom and influence of the addition of W. After designing the alloy compositions and setting the parameters, the Ti15Mo5W composition was chosen to run the experiments. The experimental Ti15Mo5W alloy was obtained by vacuum arc remelting technique using Ti, Mo and W high purity metals. The alloy was characterized by SEM, EDS and tested for Vickers hardness and compression. The microstructural characterization of the alloy proved to be homogeneous, and the mechanical characterization highlighted the obtaining of an alloy with a low elasticity modulus of about 30 GPa and an average hardness of 320 HV. |
