Abstract Scope |
Lightweight Al-Cu-Fe-Ni-Ti high entropy alloys (HEA) were developed using phase formation rules and a non-equiatomic approach. The HEAs were synthesized using an arc melting route with different concentrations of alloying elements such that one system was body-centered cubic (BCC), the second system was face-centered cubic (FCC), and the third system consisted of both (BCC and FCC) phases. The effect of the concentration of alloying elements on the microstructure and mechanical properties of HEAs was investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM)/energy dispersive spectroscopy (EDS), and compression testing. The HEAs were then homogenized using heat treatments at different temperatures, and their microstructural characteristics and mechanical properties were compared with as-cast HEAs to check the stability of different phases at elevated temperatures. A good tradeoff was observed between strength and plastic deformation. The present work helps in developing an in-depth understanding of HEAs for structural applications. |
