| Abstract Scope |
Powder metallurgy (PM) offers a growing list of benefits for the diversity of alloys possible and the ability to create complex geometries. The challenge is that powder processing methods based on templates are often complex, and simple methods, such as loose powder sintering, result in low pore volume fractions. The oxide reduction method allows individual particles to be foamed in loose form or processed by traditional PM and foamed at a later stage. The additional porosity can help bridge the gap between simplicity and performance. This method has only been demonstrated in small quantity, high-energy ball milling. In this report, we apply planetary ball milling to realize an order of magnitude increase in output with the potential for even more. The advancements in producing porosity within particles by oxide reduction, the combination with traditional porous powder methods, and the future implications for these unique materials will be discussed. |
