Description

In situ neutron diffraction measurements during tensile testing at room temperature and low temperature of a duplex stainless steel consisting of BCC and FCC phases have been performed. The deformation behavior, phase stresses and contributions of the constituent phases to the strength were analyzed and discussed. The steel showed good balance of strength and ductility at 200 K, and the phase stresses of the constituent phases at 200 K are larger than those at room temperature. Although the contributed stress to the strength of BCC phase was higher than that of FCC phase, the contribution portion to the strength of each constituent phases remained nearly constant as the test temperature changed. The strengthening with decreasing test temperature occurred in both BCC and FCC phases enhancing the work-hardening rate of the steel at low temperature. (author)
