Study of Effect and Refinement Mechanism of Rare Earth Element on Al-Ti-B-RE Refiners AITranslate
Abstract AITranslate
Study is made of the effect and refinement mechanism of rare earth element on Al-Ti-B-RE refiners prepared by casting of pure Ti particle.The results show that the addition of rare-earth element can improve the wetting quality of the molten Al to TiB2 and TiAl3 phase,and heterogeneous nucleation ability and delay decay time.The refinement result of different refiners mainly depends on the characteristic of TiB2 and TiAl3 grains,especially the morphologysize and quantity of TiAl3 phase.The refiners containing massive,small and dispersible lumpy TiAl3 phase work well,and TiB2 phase is the main factor affecting the effective nucleation quantity of α-Al.The Al-Ti-B-RE refiners are superior to Al-Ti-B refiners made both at home and abroad in respect of the refinement result and anti-recession ability.
