Description

<p>  Generally, dendritic columnar crystals and equiaxed crystals are formed in the microstructure of castings. Additionally, it is recently known that granular crystals can be obtained by giving flow. On the other hand, there are cases in which cellular columnar crystals are observed in die-castings. The difference in the forms of these primary α-Al phase may possibly change the various properties of the castings. Therefore, in this report, primary α-Al crystal of these four shapes were prepared, and these observed together with the characteristics of growth, particularly in comparison with dendritic equiaxed crystals for granular crystals.</p>
