4. Conclusions
- (1)
- A sound FSW joint was successfully obtained without any defects. The SZ was characterized by coarse-grained microstructure, and no significant nitrogen loss occurred during FSW process.
- (2)
- The grain size of SZ is larger than that of the BM and the case of SZ-top is the largest. The “onion ring” formed in the middle of SZ. Some carbides and nitrides rich in chromium were found in BM while not observed in SZ.
- (3)
- Based on the TEM, XRD and EBSD analysis, the martensitic phase in SZ could transform into austenite phase during FSW process and the higher peak temperature, the greater degree of transformation.
- (4)
- The hardness of SZ is significantly lower than that of the BM. An abrupt change of hardness defined as hard zone (HZ) was found in TMAZ on AS, and the HZ is attributed to a combination result of temperature, deformation, and material flow behavior.
- (5)
- The corrosion resistance of SZ is superior to that of BM, which can be attributed to lower precipitation and more LABs. The case of SZ-bottom is slightly higher than that of SZ-top because of the finer grained structure.
