摘要	The second phase particles TiC and TiAl3 on the refining performances of pure aluminum particles were studied in Al-TiC and Al-TiAl3 master alloys. The results show that, when TiC and TiAl3 phases are used as the α(Al) nucleation phase, both of the two nucleation capabilities are poor, but TiC particle exhibits better nucleation and higher resistance to grain refining fading than TiAl3 phase. When the second phase particles TiC and TiAl3 are used as the α(Al) nucleation phase and have a relatively quantity, they demonstrate better nucleation and higher resistance to grain refining fading. The experiments show that, in the seven groups grain refiners, the refining performances of the refiner with mole ratio of Ti to C of 1.8-1 is the best. The reason is that the TiC/aluminum interface, Ti-rich transition zone, formed by TiAl3 releasing Ti atoms in aluminum melt, Ti atoms congregating to the TiC surface, promotes the distribution of TiC in aluminum melt and advances the nucleation of TiC.
