Al-17 wt.% Ni-10 wt.% Cu alloy was prepared by melt spinning technique and characterized by X-ray diffraction, energy dispersive X-ray spectroscopy, and scanning electron microscopy. The resulting ribbon microstructure consists of intermetallic Al7Cu4Ni globular-like structure embedded within an aluminum matrix. The resulting effect of rapid solidification on mechanical properties is the enhancement of the alloy hardness up to 700 HV. The ternary phase Al7Cu4Ni exhibits hardness as high as 1300 HV.
