Abstract Scope |
Optimizing the process window for an additively manufactured material using X-ray computed tomography (XCT) is a time-, labor-, and capital-intensive process where a large number of coupons need to be analyzed in the process parameter space. Hence, as an alternative, this study aims to assess the relationship between the relative density and hardness of laser powder bed fused (L-PBF) Ti-6Al-4V. Coupons with different levels of porosity are fabricated in underheating (i.e., energy input lower than recommended), recommended, and overheating (i.e., energy input higher than recommended) conditions. These coupons are used for Rockwell hardness measurements and the results are analyzed to develop a relationship with the process window obtained via the XCT method. |
