Microstructural and Thermal Characterization of Aluminum Bronzes

In this study, microstructures and the solidification characteristics of heat treatable Cu-Al-Fe-Ni based alloys were investigated. Initial microstructural features of conventional alloys were examined by microscopical analyzes and not only martensitic structure but also several kappa phases embedded in copper based matrix were observed. Then, thermal analyzes were performed in order to reveal out the solidification sequence under cooling and the findings on the crystallization were in good agreement with the data reported earlier.
