Abstract

This paper presents an influence of Al and Ag additions on the thermal stability and devitrification behavior of Cu-Zr glassy alloy on heating. The crystallization kinetics and structure changes in Cu₅₀Zr ₄₅Al₅ and Cu₄₅Zr₄₅Al ₅Ag₅ glassy alloys on heating were studied by X-ray diffraction, transmission electron microscopy, differential scanning and isothermal calorimetry methods. The addition of Al and Ag to Cu ₅₀Zr₅₀ alloy drastically changes its crystallization behavior. It is found that Cu₅₀Zr₄₅Al₅ and Cu₄₅Zr₄₅Al₅Ag₅ glassy alloys show rather eutectic crystallization forming mostly stable phases while Cu ₅₀Zr₅₀ glassy alloy exhibits a primary crystallization behavior forming a metastable monoclimc CuZr phase at the initial crystallization stage.
