| Abstract Scope |
In additive maunfacturing, powder flowability is crucial for effective powder supply and void formation. Understanding the flowability and characteristics of powders is essential. This study compares the flowability of powders used in stack manufacturing: Inconel 625, Ti-6Al-4V, and SUS316L. Powders were produced via gas atomization and classified into sizes of 50-100μm, 100-150μm, and 50-150μm. Particle size distribution and sphericity were measured using SEM and PSA. The Avalanche method compared flowability, revealing significant variations among the alloys. Inconel 625 powder showed good flowability due to its spherical shape and narrow particle size distribution. Ti-6Al-4V powder had relatively poor flow characteristics due to irregular shapes and broader size distribution. SUS316L powder exhibited moderate flowability. Understanding these flowability differences aids in alloy selection and process optimization for stack manufacturing. This study provides valuable insights into the flowability of Inconel 625, Ti-6Al-4V, and SUS316L powders, enabling consistent and reliable powder supply in powder metallurgy. |
