Abstract

Cu59.6Zr36.9Al3.5 alloy are prepared by laser-induced combustion synthesis technology. The microstructure and phases formed of the product is studied by XRD and TEM. The product consists of mixtures of amorphous and crystalline phases, mainly(α-Zr, Zr2Cu, Zr10Cu7 and Cu8Zr3. The amorphous and nanocrystalline phases content over 50% in volume estimated from the broad peak in the XRD spectrum. TEM and HRTEM results show that the microstructure is characterized by inhomogeneously distributed amorphous, nano Zr2Cu, relatively gross (∼100 nm) Zr2Cu, and large grain Cu10Zr7.
