Controlling the formation of microstructure at the melt-pool boundaries during directed energy deposition of aluminum alloy with a modified continuous growth restriction factor

Understanding the formation of solidified microstructures adjacent to the fusion boundary of a melt pool can provide valuable insights for optimizing process parameters and achieving the desired microstructure in directed energy deposition (DED). However, existing analytical models fail to consider...
