Wear and friction are two unavoidable failures in mechanical systems with moving
components. Hence, the invention of new materials to curtail material losses and frictional …

Ultrafine-grained and heterostructured materials are currently of high interest due to their
superior mechanical and functional properties. Severe plastic deformation (SPD) is one of …

The high-entropy alloy (HEA) concept was based on the idea that high mixing entropy can
promote formation of stable single-phase microstructures. During the past 15 years, various …

Develo** microstructurally stable alloys with the outstanding strength-ductility combination
at both room temperature and elevated temperatures is highly desirable for advanced …

ABSTRACT ABSTRACT As human improve their ability to fabricate materials, alloys have
evolved from simple to complex compositions, and accordingly with improving functions and …

High entropy alloys (HEAs) are barely 12 years old. The field has stimulated new ideas and
has inspired the exploration of the vast composition space offered by multi-principal element …

High-entropy alloys (HEAs) are a relatively new class of materials that have gained
considerable attention from the metallurgical research community over recent years. They …

High-entropy alloys (HEAs) are alloys with five or more principal elements. Due to the
distinct design concept, these alloys often exhibit unusual properties. Thus, there has been …

High-entropy alloys (HEAs) can have either high strength or high ductility and a
simultaneous achievement of both still constitutes a tough challenge. The inferior castability …

This paper reviews the recent research and development of high-entropy alloys (HEAs).
HEAs are loosely defined as solid solution alloys that contain more than five principal …
