Abstract:The characteristic microstructures and formation of dispersoid of spray formed Al_93.5Cu₃Fe_1.5Ni₁Ce_0.5Zr_0.5 alloy were investigated. The observation results showed that the microstructures of deposit are fine and homogeneous and there exist three kinds of typical formation mechanisms of microstructures in deposit. The main dispersoid in deposit is AAl₁₇Cu₄FeNiCe phase with complicated cubic crystal structure whose lattice constant keeps 0.852 nm.
