Abstract

In the present study microstructures of the Cu₆₀Zr ₃₀Ti₁₀ alloy prepared by two different methods, melt spinning and injection casting has been studied by XRD, HRND, SANS, HRTEM and DSC techniques. The results show that the as-melt-spun Cu₆₀Zr ₃₀Ti₁₀ alloy consists of a fully amorphous structure, and slower cooling rate results in the formation of nanocrystals in the amorphous matrix. The maximum diameter of the rod with a glassy structure is 2 mm. The injection-cast 3 mm diameter rod consists of 10-15 nm size crystals embedded in the amorphous matrix.
