In a groundbreaking study published in ‘Materials Futures’, researchers have unveiled a novel approach to the additive manufacturing of multiscale NiFeMn multi-principal element alloys (MPEAs), which could revolutionize the construction sector by providing materials with enhanced mechanical and functional properties. This research, led by Shahryar Mooraj from the Department of Mechanical and Industrial Engineering at the University of Massachusetts, Amherst, addresses significant hurdles in the scalability and discovery of advanced engineering materials.
Mooraj and his team have developed an integrated manufacturing process that combines direct ink writing, solid-state sintering, and chemical dealloying to create hierarchically porous MPEAs. This innovative method allows for the production of materials with a unique structure featuring macro, micro, and nanoscale pores. The team’s findings suggest that these materials can be efficiently produced in large quantities, a crucial factor for commercial applications.
“The hierarchical structure we’ve developed not only enhances the material’s properties but also facilitates the efficient dealloying of a significant volume of material,” Mooraj explained. “This means that we can create complex alloys with tailored compositions that are both effective and scalable for real-world applications.”
The implications of this research extend far beyond the lab. As construction increasingly seeks materials that are lighter, stronger, and more efficient, the ability to manufacture MPEAs with customized properties could lead to advancements in everything from structural components to energy-efficient building systems. The study highlights a case where different compositions of NiFeMn MPEAs were tested as catalysts for the oxygen evolution reaction (OER), with performance varying based on composition. This discovery not only underscores the versatility of these materials but also their potential to enhance energy efficiency in construction practices.
Mooraj’s research paves the way for rapid screening and high-throughput discovery of novel functional MPEAs, making it easier for industries to find materials that meet specific performance criteria. “This approach opens new avenues for scalable fabrication, which is vital for industries looking to innovate,” he noted.
As the construction sector continues to evolve, the integration of such advanced materials could lead to significant improvements in sustainability and performance. The potential for MPEAs to reduce energy consumption and improve the longevity of structures aligns perfectly with the industry’s growing focus on sustainability.
