| Abstract Scope |
The size/shape of the melt pool and the flow behavior within a melt pool play a critical role in determining the microstructure in additively manufactured parts. However, it is challenging to experimentally characterize the physics within a metal melt pool due to its non-transparency to most of the optical-based imaging techniques. Here, with in-situ high-speed high-energy synchrotron X-ray imaging, we quantitatively characterized the melt pool and melt flow variation under different laser metal additive manufacturing conditions, and revealed the mechanisms underlying these variations. The results are critical for understanding the laser metal additive manufacturing process and beneficial for designing better processing parameters. |
