Abstract Scope |
In the electron beam powder bed fusion (EB-PBF) process, Ti-6Al-4V (Ti64) is a promising material used in additive manufacturing. This study investigates the influence of the hot isostatic pressing (HIP) process on the fatigue life of EB-PBF printed Ti64. The samples are printed with EB-PBF (Q10plus, Colibrium). Half of the samples are HIP treated by Quintus using their HIP furnace, following the ASTM-F2924-14 standard. All samples are machined to ASTM specs for fatigue testing using a 5-axis CNC machine (INTEGREX I-100ST, Mazak). The samples are tested with a rotating beam fatigue setup as the samples loaded in four-point bending using the eXpert 9300 by ADMET. The comparison of material porosity, microstructural heterogeneities, defects, and associated mechanical properties among the two groups are used to study the influence of the HIP process on 3D-printed Ti64.
