| Abstract: | Microstructures in 321 plate near weld interface of 321/Qd370qD composite plate produced by explosive welding and their formation mechanism were investigated by TEM. The results show that the mierostructures are successively amorphous phase, nanocrystal, M23 C6 phase, cementite, twins and stacking faults from the weld interface to the matrix, and fine particles exist in some regions of austenite. |
