“…It is also well known that these phases exhibit signi cant corrosion resistance, particularly under certain circumstances such as industrial atmospheres and seawater [29,30]. This makes them suitable for applications where corrosion resistance is essential, such as chemical reactions, outdoor buildings, and naval constructions [31]. A Mn-Fe-Cr rich phase was represented by the light gray patch.…”

The development of novel corrosion-resistant components is essential since malfunction of materials like super alloys during industrial applications might cause financial loss. Arc-melting and casting were used to create AlCrFeCuNi high entropy alloys (HEAs), which were then doped with various atomic percentages of copper (Cu). Investigations were conducted into the effects of Cu on the evolution of microstructural features, corrosion behavior in various solutions, nano hardness, and thermal stability. The alloy samples had a dendritic microstructure with three different phase zones, as seen by scanning electron micrographs, and EDS validated the elements that were included into the alloys. The behavior of the HEAs' nano hardness and corrosion resistance significantly improved with the addition of Cu. In NaOH and Na2SO4 solutions, 3 at.% Cu samples demonstrated superior resistance to corrosion. With NaCl and H2SO4 solutions, 5 at.% Cu samples displayed greater corrosion resistance. The sample with 1 at.% Cu showed superior corrosion resistance in HCl solution.

“…This deepened the theory of the effect of strain rate on mechanical behavior. 7,9,13,16 Furthermore, the inuence of the phase content evolution processes on the mechanical behavior at different strain rates was analyzed. From the above analysis of the effect of strain rate on the phase content evolution processes and the mechanical behavior, it can be seen that point A was the end point at which the stress and strain maintained a linear relationship and the point at which the BCC content started to decrease from 100% as well.…”

“…10 The experimental method has been widely adopted and achieved many achievements in the study of the inuence of strain rate on the elastocaloric effect of Ni-Ti-based, [11][12][13] Cubased, 14 Fe-based 15 and Ni-Mn-based alloys. 16 However, limited by the experimental method, the essence of the effect of strain rate on mechanical behavior remains unclear. As a result, it is difficult to accurately determine the variation trend of the phase transformation stage with increasing strain rates, which leads to deviations in the study of the elastocaloric effect of elastocaloric refrigeration alloys.…”
