| Abstract Scope |
One of the most common high-strength alloys used in additive manufacturing is Ti-6Al-4V. However, due to its poor thermal conductivity, high strength, and relatively low ductility, large components made of Ti-6Al-4V tend to experience cracking due to residual stresses. The near-beta titanium alloy, Ti-5Al-5Mo-5V-3Cr (Ti-5553), provides a potential solution with a lower as-printed yield strength that can be later heat treated to higher strength. To date, the mechanical properties of Ti-5553 are not documented sufficiently in the published literature. Even less information exists for additively manufactured (AM) Ti-5553.
This work studies the fatigue behavior of AM Ti-5553 with particular focus on heat treatment effects. Comparisons are made with studies in AM Ti-6Al-4V and conventionally manufactured Ti-5553. The role of flaws plays an important role in fatigue and strategies for quantifying their effects is also addressed. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. |
