The Research Progress of TiB₂ Impacts on the Refining Effect of Al-Ti-B Master Alloy

Article Preview

Abstract:

Al-Ti-B master alloy is the most widely used grain refiner in the aluminum fabrication industry, while it’s refinement mechanism is not clearly understand yet. The TiB₂ in Al-Ti-B master alloy is one of important phase to grain refining, which intimately related to the generation of initial nucleus, the “fading” phenomenon of refining effect declines with the increase of holding or standing time in grain refining process. Besides, TiB₂ is analyzed in several studies about the “poisoning” phenomenon, a large extent weaken of refining effect when Zr, Cr, Mn etc. exists. In this article, the impact of TiB₂ to the refining effect of Al-Ti-B master alloy is discussed aiming at the roles and phenomenon mentions above.
