| Abstract Scope |
The microstructure and resulting mechanical properties of additively manufactured metastable beta titanium alloys like Ti-5Al-5V-5Mo-3Cr are highly tunable through post-deposition heat-treatment. The size, distribution, and morphology of the microstructural features varies greatly with heat-treatment, requiring the meticulous development of methods for the characterization and quantification of the heat-treated microstructures. During heat-treatment the as-deposited samples were heated to temperatures (700-785°C) below the beta transus and held at sub-transus temperatures for four hours before cooling at varying rates (5-500°C/min) to room temperature. The samples were then aged for six hours at temperatures ranging from 500-650°C. The yield and tensile strengths of the heat-treated samples were measured in uniaxial tension, with yield strengths ranging from 924-1535 MPa for 28 unique heat-treatment conditions. The application of a new phenomenological equation for the prediction of yield strength will be presented to further elucidate the microstructure-property relationships of heat-treated Ti-5553 produced by laser powder bed fusion. |
