Abstract: For the first time, the study on QTi3.5-3.5graphite composite was conducted using a semi-solid processing method. The relationship between distribution of graphite particles in the ingot and solid fraction of mushy was gotten, and the condition of acquiring QTi3.5-3.5graphite composite with evenly-distributing graphite particles was determined. The results showed that the rising-gathering of graphite particles reduced gradually with the increasing of solid fraction. When solid fraction was larger than 40 %, the rising-gathering of graphite particles could be removed, and QTi3.5-3.5graphite composite with evenly-distributing graphite particles could be gotten.
