| Summary: | The importance of High Entropy Alloys extends beyond their impressive properties. They represent a paradigm shift in materials science and metallurgy. Alloys containing four or more primary elements are referred to as High Entropy Alloys (HEA). The concentration of each major component should range from 5 to 35 at.%. HEAs may have minor constituents, each below 5 at.%, in addition to primary elements. HEAs offer a platform for innovation in materials design. Their tunable properties and unique compositions allow engineers to think creatively and address complex challenges in various industries. HEAs have pushed the boundaries of materials science and processing techniques. Their complex compositions have encouraged the development of advanced manufacturing processes and technologies. HEAs allows for the combination of multiple elements, it is possible to produce different variations of alloys that were not achievable with conventional alloys. This allows for the exploration of various element combinations. resulting in the alloys' discovery with adaptability and flexibility according to the specifications of the design. The integration of additive manufacturing with high HEAs has unlocked new possibilities, offering improved performance, complex geometries, and sustainable production.
In this paper, we will discuss the fabrication of high entropy alloys, more specifically the addition of Nb to a MEA CoCrNi to form the HEA, CoCrNiNbx. Moreover, we aim to better understand the microstructure and mechanical properties of compositionally graded HEA CoCrNiNbx. There will be a series of microstructure and mechanical experiments conducted on the alloy. Thus, studying the effect Nb has on the MEA CoCrNi with varying concentrations.
