The alloys with Ti, Zr separate and combined micro-alloying were prepared by ingot metallurgy method. The effect of Ti, Zr separate and combined addition on the grain refinement and anti-fading performance of grain refinement was investigated and compared by metallographic microscope (OM), scanning electron microscopy (SEM), energy spectrum (EDS) and X-ray diffraction (XRD) and other means. The results show that Ti, Zr composite added possesses more excellent grain refining effect and more significant anti-fading performance of grain refinement than that of Ti, Zr added alone. When holding time up to 110minute, the Al-0.15Zr-0.15Ti alloy still keeps effective grain refinement effect.
