Abstract Scope |
Titanium alloys are commonly sought for their specific strength and used in applications where weights savings may be achieved with only a moderate reduction in strength. Following heat treatments, this work has demonstrated that the uniaxial tensile properties, specifically the yield and tensile strengths, of metastable beta titanium alloy Ti-5Al-5V-5Mo-3Cr produced via selective laser melting begins to surpass those of high strength steels. The yield strengths range from 924-1535 MPa for 28 selective laser melted samples that experienced post-deposition heat-treatments. The wide range of measured mechanical properties can be rationalized through careful observation and analysis of the heat-treated microstructures. The observations, including detailed characterization, and a new equation to predict the strength of Ti-5553 will be presented. |
