Effect of laser intensity profile on the microstructure and texture of Inconel 718 superalloy fabricated by direct energy deposition
Epitaxial growth of dendrites often results in a strong texture, which is a common phenomenon in a laser additive manufacturing process.In this study, pulsed lasers with flat-top and Gaussian intensity profiles were used to modulate the molten pool morphology and the solidification texture with a unidirectional scanning strategy.The melt pool is pl
