Sažetak

It was found that concentration of boron in aluminium with the addition of AlTi₅B₁ grain refiner is decreasing during remelting as a consequence of TiB₂ particles settling down due to gravity. TiB₂ particles remained in aluminium after four remelts shows lower effect of grain refinement compared to non-remelted samples with the same TiB₂ content. It was also found that TiC particles are still present in aluminium with the addition of AlTi3C0,15 grain refiner after four remelts and they probably participate in nucleation of α-Al grains.
