Abstract

Partially crystalline metallic glass ZrCu was prepared in the form of ribbons by melt-spinning. The chemical composition and homogeneity of the samples alongside partial crystallinity with the existence of an amorphous matrix was confirmed. The measured value of microhardness shows a nonlinear dependence with the increase of Cu. By adding a small fraction of Al the glass forming ability of this binary metallic glass increases. The thermal stability was examined using differential scanning calorimetry.
