In our previous study, a novel Al-L1(2)-type Al2.7Fe0.3Ti refiner was fabricated by spark plasma sintering (SPS) and its refining performance was studied. It was found that L1(2)-type Al2.7Fe0.3Ti particles can be favorable heterogeneous nucleation sites for Al casts, since the lattice matching between Al2.7Fe0.3Ti 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 Al2.7Fe0.3Ti phase in a refiner are studied by heating an Al-Al2.7Fe0.3Ti refiner fabricated by SPS. In addition, the refining performance of a heated Al-Al2.7Fe0.3Ti refiner is investigated.
