Abstract Scope |
The temperature and material flow field are computed using the heat transfer and material flow model for the directed energy deposition process. The solidification parameters, such as thermal gradient and solidification rate are computed along the melt pool fusion line to determine the solidification morphology. The effect of preheat temperature on the solidification morphology is analysed with the developed model. The model predicts columnar morphology for deposition of Al-0.5Sc-0.5Si alloy with room temperature substrate. However, the presence of equiaxed morphology is predicted with increasing substrate preheat temperature. The size of the morphology also varies from bottom to top for varying melt pool size. The solidification morphology predicted using computation agrees with the experimental observations. |
