| Abstract Scope |
we used synchrotron X-ray diffraction and tomography simultaneously to study in real-time the multiphase dynamic evolution of Al-Fe-Mn-Si multicomponent alloys during the solidification process. The onset of phases nucleation was identified in-situ by diffraction. Then the subsequent growth of the phases in 3D space can be tracked by tomography in real-time. As the solidification proceeds, the 3D morphology and the spatial relationship of those phases were continuously monitored and recorded. In this way, the whole nucleation and phase growth dynamic process of the multiphases in 3D space can be systematically studied. The research provides comprehensive structure evolution information for us to fully understand the formation of the complex structures in such alloy system which is essential for the alloy design and optimization. |
