| Abstract Scope |
Efforts were made to successfully optimize friction stir welding (FSW) technique with regard to joining Ni-based ODS MA754 alloy. Microstructures and mechanical properties of the parent and processed materials (i.e., friction stir welded) were characterized earlier, and the results showed that FSW did not significantly degrade MA754, unlike fusion welding. Later, we won a NSUF irradiation experiment award to perform neutron irradiation (1 dpa and 2.5 dpa) on parent and friction stir processed ODS MA754. The objectives of this project are to obtain two critical information: neutron irradiation behavior of Ni-based ODS alloy and potential of FSW for nuclear applications. Currently, efforts are ongoing to understand the microstructural evolution and concomitant changes in mechanical properties of parent and friction stir processed MA754 after neutron irradiation. |
