| description | The invention discloses narrow particle size distribution GH4099 high-temperature alloy powder for additive manufacturing as well as preparation and application of the narrow particle size distribution GH4099 high-temperature alloy powder. The invention belongs to the field of GH4099 high-temperature alloy powder and preparation thereof. The invention aims to solve the technical problems of poor batch stability, ceramic inclusion and formed part cracking of the existing high-temperature alloy powder for additive manufacturing. The narrow-particle-size-distribution GH4099 high-temperature alloy powder for additive manufacturing is prepared from, by mass, 0.03%-0.05% of C, 17%-20% of Cr, 5%-8% of Co, 5%-7% of W, 3.5%-4.5% of Mo, 1.7%-2.1% of Al, 1%-1.35% of Ti and the balance Ni and impurities, and the alloy powder with the particle size being 30-53 micrometers accounts for 59 wt%. The method comprises the step of preparing the alloy powder through a plasma rotating electrode. The alloy powder is used for addit |
