Solidification morphology

Microstructure engineering during directed energy deposition of Al-0.5Sc-0.5Si using heated build platform

Achieving a specific solidification morphology during the directed energy deposition process can be key to desired properties of the deposited part. The careful control of thermal gradient and cooling rates can be utilized to achieve these grain …

Investigation of temperature distribution and solidification morphology in multilayered directed energy deposition of Al-0.5Sc-0.5Si alloy

The temperature distribution, geometry and size of the melt pool, and solidification parameters were computed using the heat transfer and material flow model for the directed energy deposition process. The thermal cycle and melt pool size were …
