摘要

The microstructure morphology of SAF2205 steel during single direction torsion is studied at room temperature by optical microscope. The microstructure evolution indicates that different austenite morphologies on selected longitudinal sections are observed from the subsample close to clamp end, the subsample close to the fracture end and the subsample from the undeformed specimen. The austenite is elongated gradually on longitudinal sections which caused by shear stress. Concurrently, the elongation degree is more obvious in L1 section (near to the center of the sample) than that of L2 section (away from the center of the sample), which is attributed to the gradient distribution of plastic strain. The finite element analysis shows the plastic strain distribution law of the torsional deformation and the results from the fracture appearance indicate the dimples with different depths and types are observed.
