The team has introduced the idea of the Hyperadaptor and created a nickel-based high-entropy alloy.
This material demonstrates nearly constant mechanical performance across cryogenic and high heat temperatures.
Stable Mechanical Performance Across Temperature Extremes
The stability of the Hyperadaptor alloy is due to the presence of nanoscale L1₂ precipitates, which are evenly distributed across the alloy.
The fine particles act as reinforcements that inhibit deformation, with the alloy's internal structure accommodating the stress through consistent slip behaviour, regardless of temperature.
Applications in High-Temperature Industries
This material can be applied to products that undergo extreme temperature shifts, such as jet engines and power plant turbines.
The Hyperadaptor can help to enhance both safety and efficiency in these demanding environments.
Breakthrough and Future Potential of the Hyperadaptor
"Our HEA breaks through the limitations of existing alloys and establishes a new class of temperature-insensitive materials," said Professor Kim.
"The Hyperadaptor concept represents a breakthrough in developing next-generation materials with consistent mechanical behaviour even under extreme conditions."
The study was supported by the Ministry of Science and ICT through the Nano and Materials Technology Development Program and by Hyundai Motor Group.
