ORNL worked with Quintus Technologies to develop new hot isostatic pressing parameters for Ti-6Al-4V components fabricated via Arcam electron beam melting. These parameters result in isotropic tensile behavior compared to the conventional hot isostatic press HIP parameters that result in anisotropic tensile properties depending on the build direction. Furthermore, an improvement in fatigue behavior was observed.
