To investigate the tensile deformation behavior of a lean duplex stainless steel (S32101) from the viewpoints of plastic deformability among phases or grains, we performed static tensile tests, in situ neutron diffraction, and white X-ray diffraction experiments at room temperature. From the experimental results of synchrotron radiation white X-ray diffraction experiments, the hard phase of S32101 was changed from the ferrite phase to austenite one during tensile deformation. This led to a larger stress partitioning between the phases at the latter stage of deformation. From the experimental results of in situ neutron diffraction, it was found that the stress partitioning of the $$gamma$$ phase in the S32101 was the largest among the present results. Therefore, the larger work hardening rate of S32101 can be explained by the large stress partitioning of the $$gamma$$ phase, that between $$gamma$$ and $$alpha$$ phases and $$gamma$$ volume fraction.

TRIP steel deformation behavior by neutron diffraction

Harjo, S.; Tsuchida, Noriyuki*; Gong, W.; Abe, Jun; Aizawa, Kazuya

Materials Research Society Symposium Proceedings, Vol.1528 (Internet), 7 Pages, 2013/01

Transformation Induced Plasticity (TRIP) is one of important effects of steel strengthening mechanism to improve strength, ductility and excellent high-speed deformation behavior. To measure strengthening mechanism of TRIP steel during deformation, in situ neutron diffraction measurement during tensile deformation was performed. Two kinds of TRIP steels with different carbon content were prepared. Neutron diffraction measurements were performed using beamline 19 TAKUMI, a pulsed-neutron TOF diffractometer in J-PARC. Detail results will be shown and discussed during presentation.
