| Abstract Scope |
The AlCrFeNi eutectic HEAs have been designed by the introduction of 1, 3, 5 at% Mo and Ti, and their mechanical behaviors were investigated along with double-phase strengthening. The X-Ray Diffraction analysis demonstrated the presence of B2 and BCC dual phases. Compositional variation by the addition of minor elements such as Mo and Ti resulted in the formation of the eutectic structure. The high degree of coherence in dendritic and lamellar regions of the nanoscale Al-Ni-rich B2 phase and Cr-Fe-rich A2 phase was proven by the results of in-detail investigation of the nanostructural evolution of the alloy. Variation in the grain size highlights fraction combined with the addition of the minor elements exhibit good hardness behavior at elevated temperatures which highlights the enhancement of the mechanical properties of the new alloy. |
