| Abstract: | he irifluence of crystallographic orientations on dendritic morphologies in a SC suporalloy has been in-vestigated. The results indicate that,an obviotis change of the geometrical arrangement of primary den-drites and unsymmetric secondary arms occur for different crystallographic orientations. |
