Abstract

The effect of Zr addition on the grain refinement of commercial pure aluminium (99.7%) has been investigated in the present study. The results showed that addition of up to 0.3wt. % Zr significantly decreases the average grain size of aluminium from 1100 μm to 162 μm at holding time of 90 seconds. The refining effect of zirconium is attributed to the presence of Al3Zr particles in Al-Zr master alloy. These particles are acting as effective heterogeneous nucleating sites for α-Al.
