Abstract
A kind of A1-5H-0.3C master alloy with uniform micro structure has been prepared using a new technology. The pre-nucleating TiC particles with an average size of about 0.3pm are dispersed homogeneously in the a-AI matrix. This new A1-5H-0.3C master alloy has great refining performance on aluminum alloys. It is found that the average grain size of 6063 alloy can be reduced from 3000pm to 40pm by the addition of the prepared A1-5H-0.3C master alloy and the refining efficiency does not fade obviously within 60 min. Furthermore, the mechanical properties and corrosion resistance of 6063 alloy are also improved. The ultimate tensile strength and hardness of the 6063 alloy can be largely improved from 170MPa, 35 to 271MPa, 81.7, respectively. In addition, the corrosion resistance is also enhanced largely. Finally, the possible mechanisms are also discussed.
