   Microstructure and mechanical properties of High-Entropy Alloys


High Entropy Alloys (HEAs) are in the focus of materials science due to 
their high strength, good ductility and excellent resistance to wear, 
corrosion and softening at high temperatures. HEAs are disordered solid 
solutions, containing at least five chemical elements with similar 
concentrations. The goal of our study was to investigate the influence 
of plastic deformation on the microstructure and hardness of the HEAs. 
The evolution of the grain size and the dislocation density was studied 
by electron microscopy and X-ray line profile analysis. We have 
investigated the relationship of the mechanical behaviour, the 
microstructure evolution and the dislocation density in High-Entropy 
Alloy after plastic deformation.
