Effects of solidification MicrostructureParameters of Aluminum-based multicomponent alloys (Al-Mg-Si; Al-Sn-Cu; Al-Zn-Mg) on the resistances to Corrosionand tribocorrosion degradation

Abstract

With the comprehension of microstructural parameters of alloys directionally solidified under transient heat flow conditions, it is possible to envisage components having better properties and higher lifetime. A careful study, permitting correlations between these microstructural parameters and mechanical, wear, corrosion and tribocorrosion behavior of metallic alloys to be established, is fundamental in the pre-programming of final properties of as-cast components. In particular Al-based multicomponent alloys have important application in the automotive, aeronautics and naval industries, with multiple demands with respect to mechanical and corrosion resistances and tribological properties. However, there are no systematic studies in the literature on the evolution of solidification microstructures under transient heat flow conditions and on correlations between the scale of parametric features of these microstructures and application properties such as wear and corrosion resistances. The present study aims to develop a detailed analysis of the microstructural evolution of different compositions of Al-Sn-Cu; Al-Mg-Si e Al-Zn-Mg alloys directionally solidified under transient conditions. The study also aims to establish growth laws correlating quantitative parameters of the microstructure and solidification thermal parameters. Furthermore, representative specimens of each alloy examined having different microstructural scales (e.g. dendritic or interphase spacings) will be subjected to corrosion and tribocorrosion tests with a view to determining correlations between these microstructures and the corresponding corrosion and tribocorrosion behavior. The tribocorrosion tests will be carried out in the Centro Nacional de InvestigacionesMetalurgicas - CENIM de Madri, through a scientific partnership already established. (AU)
