#3 Metal Powders Technologies and Applications - AMAZEMET Academy

Is industrial atomization blocking your R&D? 🔬 Welcome to Episode #3 of the "Researcher's Guide to In-house Metal Powder Production." 🧑‍🏫 Designing new alloys is a critical research field in metallurgy right now. However, when it comes to early-stage alloy development, standard gas atomizers are simply too large to diligently carry on research. This is where ultrasonic atomization changes the game. With the *AMAZEMET rePOWDER* platform, you can produce highly spherical metallic particles in small batches, perfectly optimized for advanced additive manufacturing and other powder metallurgy methods. In this episode, Łukasz Żrodowski looks at the physics behind particle morphology. He explores the critical role of powder characteristics across different powder metallurgy methods. In Episode #3, we cover: ◾ Gas vs. Ultrasonic Atomization:** Why industrial gas atomizers are often too large for R&D, and how tools like the rePOWDER platform provide spherical particles for agile, lab-scale alloy development. ◾ AM Process Stability & Rheology:** How highly spherical, free-flowing powder is vital across all AM methods. It prevents porosity in *LPBF* , stops the "smoke effect" in *EBM* , ensures stable nozzle flow in *DED* , and maximizes packing density to control shrinkage in *Binder Jetting* ◾ Versatility Across Methods:** By changing the frequency, you can fine-tune the particle size for specific technologies. For example, 40kHz is our standard for LPBF, while 20kHz is primarily used for Electron Beam Melting (EBM) and Direct Energy Deposition (DED). ◾ Advanced Alloy Creation:** Getting pre-alloyed spherical powders allows you to bypass lengthy mechanical alloying tasks. This is a powerful tool to swiftly create new High Entropy Alloys (HEAs) and intermetallics for Spark Plasma Sintering (SPS) or Hot Isostatic Pressing (HIP). Better powder, better results.
