In the quest to enhance the performance and versatility of amorphous alloys, a team of researchers led by Inga E. Permyakova from the Baikov Institute of Metallurgy and Materials Science of RAS in Moscow has delved into the intriguing world of ultrasonic treatment. Their findings, published in the journal *Frontiers in Materials and Technologies* (translated from Russian), offer a promising path forward for these unique materials, with significant implications for the energy sector and beyond.
Amorphous alloys, also known as metallic glasses, are prized for their exceptional strength and corrosion resistance. However, their narrow thermal stability range, brittleness at high temperatures, and low tensile plasticity have posed challenges to their widespread application. Enter ultrasonic treatment, a innovative method that might just unlock the full potential of these alloys.
Permyakova and her team have systematically reviewed the effects of ultrasonic vibrations on the structural transformations and mechanical behavior of amorphous alloys. “Ultrasonic treatment can contribute to the improvement of the operational properties of amorphous alloys, their manufacture at different scale levels, and high-quality joining with other materials,” Permyakova explains. This treatment could potentially enhance the formability of these alloys, achieving a delicate balance between plasticity and strength, and even enabling their consolidation with other metals.
The research highlights several promising applications for ultrasonic technologies in the near future. These include additive manufacturing of amorphous alloys, the creation of hybrid composites through ultrasonic welding, and ultrasonic forming for producing complex shapes and geometries. Moreover, complex multi-stage processing, such as melt quenching followed by laser irradiation and ultrasonic stimulation, could yield a unique combination of properties tailored to specific applications.
The energy sector stands to benefit significantly from these advancements. Amorphous alloys with enhanced properties could lead to more efficient and durable components for energy generation, transmission, and storage systems. For instance, improved corrosion resistance could extend the lifespan of critical infrastructure, while enhanced formability could enable the creation of intricate components for advanced energy technologies.
However, the researchers also acknowledge the limitations of current studies and the need for further investigation. “The effect of ultrasonic vibrations on structural transformations and mechanical behavior of amorphous alloys is not completely understood,” Permyakova notes. “The lack of an integrated scientific basis for the physical processes and accompanying effects in amorphous alloys under ultrasonic excitation prevents the development of the corresponding technology and optimization of its modes.”
As the scientific community continues to explore and refine ultrasonic treatment techniques, the future of amorphous alloys looks brighter than ever. With ongoing research and development, these materials could soon find their way into a wide range of applications, revolutionizing industries and shaping the technologies of tomorrow. The work of Permyakova and her team, published in *Frontiers in Materials and Technologies*, serves as a crucial stepping stone in this exciting journey.
