The microstructural features and mechanical properties of three groups of melt-spun Al-Fe-Si-V ribbons were investigated in order to enhance its optimization for elevated temperature applications and their variation with process variables noted. The influence of cooling rate, heat treatments on the microstructure and mechanical properties are discussed. From the combined studies of microstructure, DSC, XRD and theoretical correlations on the crystallization behaviors of these group of ribbons, it can be concluded that the melt spinning conditions and determines the crystallization behaviors and hence the microstructure. Thus, the characterization results of the three batches of melt-spun corresponding to the flakes produced in 2003, 2004 and 2005, respectively, varied significantly. It was concluded that the melt-spinning conditions were responsible for the variations in the microstructures and mechanical properties of the ribbons.
