The electromagnetic-mechanical stirring technology was employed for preparing QTi4.3-4 graghite composite slurry, and QTi4.3-4 graghite composite with uniform distribution of graphite particles was prepared using the semi-solid casting technology successfully. The structure of this QTi4.3-4 graghite composite was studied and the condition for uniform distribution of graphite particles was got. The experimental results show that there exists a linear relationship between the solid fraction aud the stirring temperature of QTi4.3-4 graphite slurry. With the decreasing of stirring temperature, the solid fraction of QTi4.3-4 graghite slurry increases constantly. In casting, with the iucreasing of solid fraction of QTi4.3-4graghite slurry, the agglomeration of graphite particles is removed gradually. When the solid fraction is higher than 40% , graphite particles can distribute evenly in QTi4.3-4 graghite composite.
