| Abstract Scope |
The recently discovered heteroepitaxial recrystallization (HeRX) mechanism was originally described as a curiosity that only happened under narrow conditions. However, this experimental and characterization work illustrates that it is active under a much wider range of conditions. Furthermore, the activity of this mechanism can be controlled via changes to the processing schedule, resulting in substantial changes to the shape of the grain size distribution. Further controlling this mechanism offers a new avenue for the control of grain size and the resulting mechanical performance of superalloys. |
