Abstract Transformation induced plasticity(TRIP) duplex stainless steel has great potential for industrial application because of its excellent strength and plasticity and economic efficiency. The effect of martensite transformation during cyclic deformation on cyclic mechanical properties of TRIP duplex stainless steel is the basis of promoting its further development and industrial application. Thus the cyclic properties and transformation characteristics of TRIP duplex stainless steel Fe-19Cr-0.2 Ni-5Mn-0.2Si were studied. The tensile mechanical properties and cyclic softening/hardening properties under symmetrical cyclic loading test with 0.6% strain amplitude of the tested steel were determined by INSTRON test machine,respectively. In the process of cyclic loading,the martensitic transformation was measured by ferrite measuring instrument at different cycles,and the characteristics of martensitic transformation were analyzed. Transmission electron microscopy (TEM) was used to observe the microscopic structures of transformation martensite and dislocation under typical cycles. Furthermore,the mechanism of martensitic transformation and dislocation structure evolution on cyclic softening and hardening properties was studied. The results show that the test steel shows obvious TRIP effect under tensile condition. The martensite transformation rate is fast at the early stage of cycling,and then the transformation rate gradually decreases and tends to zero. Cyclic softening and hardening can be divided into three stages: initial cyclic hardening,cyclic softening and secondary cyclic hardening. The hardening effect caused by the proliferation of dislocations in the two phases plays a leading role in the initial cyclic hardening. The subsequent cyclic softening is dominated by the softening effect caused by the low energy dislocation structure in ferrite. In the secondary cyclic hardening stage,the transformation martensite plays a leading role in the hardening of the material. Although transformation martensite has little effect on the cyclic softening and hardening properties of the tested steel at the early stage of cyclic loading,it has a great effect on the properties at the later stage of cyclic loading.
