High entropy alloys or HEAs consist of five or more different metallic elements and are an extremely interesting class of materials with a great diversity of potential applications. Since the ...

The traditional approach to materials design is to start with a base composition and then tune its chemistry by adding smaller amounts of other elements or compounds. However, a new approach has ...

Aircraft engines work better at higher temperatures. As they get hotter, they burn fuel more efficiently, which means they can fly farther on the same volume of propellant. But they can’t get too hot ...

We are surrounded by a variety of alloys in our everyday lives. Brass for example, is made from copper and zinc, while stainless steel is a mixture of iron and chromium. The majority of these alloys ...

Supercomputer simulations are helping scientists discover new high-entropy alloys. XSEDE allocations on TACC's Stampede2 supercomputer supported density function theory calculations for largest ...

A new generation of refractory alloys with excellent high-temperature performance is urgently demanded for aero-engines, gas turbines, and nuclear power plants. As the service temperature of their hot ...

(Nanowerk Spotlight) Liquid metals have long fascinated materials scientists due to their unique properties that bridge the gap between solid and liquid states of matter. These materials, which remain ...

In this interview, industry expert Chulyong Sim explores groundbreaking advancements in high entropy alloy development, highlighting new methods that can drastically reduce production time and enhance ...

Compressing hydrogen demands high pressures; liquefying it requires extreme cooling. Both approaches carry energy penalties, safety considerations, and infrastructure costs that limit wider adoption.

High-entropy alloys (HEAs) are promising materials for catalysis and energy storage, and at the same time they are extremely hard, heat resistant and demonstrate great variability in their magnetic ...

The term “high entropy” refers to the fact that these alloys contain five or more elements in roughly equal amounts, resulting in a complex microstructure and high configurational entropy. This high ...
