EFFECT OF LASER INTENSITY PROFILE ON THE MICROSTRUCTURE AND TEXTURE OF INCONEL 718 SUPERALLOY FABRICATED BY DIRECT ENERGY DEPOSITION

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
