The chemical segregation in the dendritic structure is correlated to strain heterogeneities after creep experiments on ultrathin specimens. It is shown that primary dendrite axes have a strengthening effect. References 1 F. I. Versnyder, M. E. Shank, Mater. Sci. Eng. 1970, 6, 213. 2 P. Caron, T. Khan, J. L. Raffestin, in.
