Abstract

Abstract: In our previous study, a novel Al-L12 -type Al2.7 Fe0.3 Ti refiner was fabricated by spark plasma sintering (SPS) and its refining performance was studied. It was found that L12 -type Al2.7 Fe0.3 Ti particles can be favorable heterogeneous nucleation sites for Al casts, since the lattice matching between Al2.7 Fe0.3 Ti and Al is good. It was also found that the thermal stability of heterogeneous nucleation sites affects the grain-refining performance. In this study, the decomposition phenomena of the Al2.7 Fe0.3 Ti phase in a refiner are studied by heating an Al–Al2.7 Fe0.3 Ti refiner fabricated by SPS. In addition, the refining performance of a heated Al–Al2.7 Fe0.3 Ti refiner is investigated.
