キーワード：
multi-beam laser directed energy deposition (MBL-DED)、substrate heating、laser focal positioning、high-entropy alloys (HEA)、meltpool control
Optimization of multi-beam laser DED parameters, including substrate heating and laser focal position, enhances bead quality, minimizes meltpool formation, and prevents Fe incorporation in HEA bead.
