摘      要：A kind of micro/nanostructured 2205 duplex stainless steel(DSS)with uniform distribution of nanocrystals was prepared via aluminothermic reaction *** analysis of stress-strain curve showed that the fracture strength and elongation of the specimen were 946 MPa and 24.7%,*** present,the research on microstructure of bimodal 2205 DSS at room temperature(RT)mainly depended on scanning electron microscope(SEM)observation after loading *** test result indicates that there are two different yield stages in stress-strain curve of specimen during tensile *** microstructure of duplex bimodal structured stainless steel consists of two pairs of soft hard regions and *** studying deformation mechanism of bimodal structured stainless steel,the interaction between soft phase and hard phase are *** principle of composition design and microstructure control of typical duplex stainless steel is obtained,which provides an important research basis for designing of advanced duplex stainless steel.
