Abstract Scope There is increasing interest in the use of additive manufacturing (AM) for superalloys due to their broad applications in the aerospace industry. As the raw materials, high-quality metal powder is very important for successful selective laser melting in AM. In this work, Haynes 230 powders manufactured by VIGA and PREP were characterized and compared. Results demonstrated P-230 powder is superior to V-230 powders. P-230 powder exhibits the lower Hausner ratio and better flowability. Meanwhile, attributed to superior sphericity and fewer satellite particles, lower dynamic angle of repose and cohesive index were achieved by P-230 powder, which means better dynamic flow and spreading of the powder during the recoating process of selective laser melting (SLM). In terms of their performance on SLM, the powder bed density of the P-230 powder is higher, and samples prepared with P-230 powder exhibited higher relative density. Although both V-230 and P-230 samples were all HIPed at 1200℃ for 4h, P-230 samples revealed much higher yield strength at room temperature.
