Although HEAs were considered from a theoretical standpoint as early as 1981 and 1996, and throughout the 1980s, in 1995 Taiwanese scientist Jien-Wei Yeh came up with his idea for ways of actually creating high-entropy alloys, … See more

Due to their multi-component composition, HEAs exhibit different basic effect than the other traditional alloys that are based only on one or two elements. Those different effect are called "the four core effects of HEAs" and are behind a lot of the particular … See more

High-entropy alloys are difficult to manufacture using extant techniques as of 2018 , and typically require both expensive materials and … See more

CALPHAD (CALculation of PHAse Diagrams) is a method to create reliable thermodynamic databases that can be an effective tool when … See more

There is no universally agreed-upon definition of a HEA. The originally defined HEAs as alloys containing at least 5 elements with concentrations between 5 and 35 See more

In conventional alloy design, one primary element such as iron, copper, or aluminum is chosen for its properties. Then, small amounts of additional … See more

The atomic-scale complexity presents additional challenges to computational modelling of high-entropy alloys. Thermodynamic modeling using the CALPHAD method requires extrapolating from binary and ternary systems. Most commercial … See more
