Directional and oscillating residual stress on the mesoscale in additively manufactured Ti-6Al-4V

.
.

In this work, we were able to improve existing residual stress measurement capabilities so that we could measure smaller length scales. We were able to measure residual stresses that oscillated from build layer to build layer (0.5 mm thick) in an additively manufactured part. The oscillations persisted over nearly 30 layers!
