Evidence of High-Temperature Strain Heterogeneities in a Nickel-Based Single-Crystal Superalloy
Résumé
The creep behavior of a single crystal superalloy is investigated at the dendritic scale. 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.
