Al CrFeNi eutectic multi-component alloys were prepared to obtain excellent mechanical properties by double phase strengthening. The X-ray diffraction results showed that the crystal structure were both body-centered cubic and energy-dispersive X-ray spectrometer identified that the two phases are ordered NiAl intermetallic and disordered [Fe, Cr] solid solution. The formation of eutectic structures was introduced by a simplified dynamic model. After mechanical tests, the alloys presented excellent compressive strength and unexpected large deformation. Due to the solid solution and fine-grain strengthening resulted by Al addition, mechanical properties of Al CrFeNi alloys exhibited regularity in some degree. Among all alloys, Al1.3CrFeNi has the highest fracture strength and Al0.9CrFeNi has the most excellent strain. Besides, Al1.2CrFeNi alloy showed a good combination of strength and ductility.
