| Abstract Scope |
In recent years, attention has been given to the production of unique alloy powders for additive manufacturing, tailored to extreme temperature resiliency or smart material functionality. Conventional methods for producing powders are based on gas, water, and ultrasonic atomization. The first two are limited by high levels of oxidation and unpredictable morphology, undesirable for creating powders for additive manufacturing. In recent years, ultrasonic atomization has gained attention due to its ability to create powders with a predictable morphology and minimal oxidation. For this research, an investigation is conducted to study the ultrasonic atomization of a group of unique alloys, including a variety of refractory high-entropy alloys, pre-processed using cold-crucible vacuum arc melting. Characterization of morphology and elemental distribution is performed using scanning electron microscopy and x-ray diffraction, grading the process for successfully creating powders with predictable characteristics suitable for additive manufacturing. |
