| Abstract Scope |
The eutectic structure has been developed by adding minor elements such as Mo and Ti at 1, 3, and 5at% to the AlCrFeNi high entropy alloy. The aim of the work was to study mechanical behavior with double phase strengthening. The presence of B2 and BCC dual phases in the crystal structure was confirmed by an X-ray diffraction test. The addition of minor elements leads to the formation of eutectic alloy that is manifested by compositional variation in the alloy. The high degree of coherence of the morphology of the nanoscale Cr-Fe-rich A2 phase and Al-Ni-rich B2 phase in dendritic and lamellar regions was discovered during further analysis of the nanostructural evolution of the alloy. High-temperature hardness behavior was committed by the enhancement of mechanical properties being a result of variation in size of the grain on the nanoscale and volume fraction variation produced after adding minor elements. |
