Abstract

In this paper, real-time, direct observation of the nucleation of primary Al 2 Cu phases on entrained oxide films during the solidification of an Al-35%Cu alloy, and the change of growth mode from planner to dendritic type structure of Al 3 Ni phases in an Al-15%Ni alloy under a pulse magnetic field are presented and discussed. Real-time synchrotron X-ray radiography provides clear and unambiguous evidence to confirm that the entrained oxide films can indeed directly nucleate primary Al 2 Cu intermetallic phases. Combining radiography and tomography together, the critical conditions of changing growth mode from a planner to dendritic type for the Al 3 Ni phases were also clearly revealed. The research demonstrates that synchrotron X-ray-based real-time characterisation techniques are the indispensable tools for quantitative solidification research.
