Abstract Scope |
We present a data-driven multiscale computational framework based on discrete dislocation dynamics (DDD) for investigating the effects of irradiation on the mechanical behavior of small scale FeCrAl specimens. Irradiation induced defects such as a/2<111> and a<100> prismatic loops, and composition fluctuations/α’ precipitates play a critical role in governing the mechanical behavior of alloys hence influencing their in-service longevity in nuclear environments. This along with the size effects in small scale specimens make the irradiation physics more intriguing. In this presentation, we report on the combined as well as separated effects of different irradiation induced defects along with the effects of loading orientations on the mechanical behavior of the irradiated nanoscale FeCrAl alloys. |
