Fig. 11.40 Transverse cross section of the ring presented in Fig. 11.39 . Dendritic structure. Some changes in the as-cast structure, produced by the hot working, can be seen in the region to the right of the macrograph (ring surface). Etchant: hot hydrochloric acid. More

no indications of the previous dendrites in the macrograph. As one moves to the center of the forging (where the solidification times were longer in the ingot, and where sometimes the deformation is lower), residues of the dendritic structure can be seen.
