Popis:	Microstructure evolution of friction stir processed 2507 duplex stainless steel was investigated at rotational speed of 400 rpm and traverse speed of 100 mm/min. The microstructural evolution in processed zone was studied by optical microscopy and electron backscattered diffraction. Regions in the stir zone and the thermo-mechanically affected zone experienced different microstructure evolution due to different thermo-mechanical processes. The results showed that static recrystallization, dynamic recrystallization, and dynamic recovery occurred in the processed zone. And the ferrite was occurred the recrystallization prior to the austenite.
