“…In both papers, the phase changes and precipitation events were shown to take place in the ferrite phase only. Under 50% of reduction in thickness, cold rolling produces band‐like regions of dislocations in the austenite phase and cell‐like dislocation structures in the ferrite phase .

Deformation-Induced Role Switching Between Ferrite and Austenite in the Precipitation of Carbides at High Temperatures in Duplex Stainless Steels

The austenite phase of duplex stainless steels is commonly considered to undergo nearly no precipitation events upon thermal annealing, whereas the ferrite phase is invariably viewed as the transforming phase. The present paper shows that the situation will be the opposite after plastic deformation and annealing at temperatures above 900 8C. The role switching in terms of carbide precipitation may be explained on grounds of the more efficient diffusion of substitutional elements brought about by dislocations and the abundance of carbon atoms in the austenite phase.

The effect of solution temperature on cold rolling properties of lean duplex stainless steel (LDSS) was studied. The cold‐rolling test was used to observe the crack of the material after solution at different temperatures; the work hardening curve of the solution treated material was obtained by compression test at room temperature, and the austenite element in LDSS was calculated by Thermo‐Calc software. The different element contents obviously affect the stacking fault energy (SFE) of the materials, which leads to the change of the difficulty of transformation induced martensite in austenite. The phase transformation induced plasticity (TRIP) effect in LDSS was analyzed by optical microscopy (OM), transmission electron microscopy (TEM), and electron backscatter diffraction (EBSD). It is found that different solution temperature can significantly affect the grain size of austenite, and then affect the difficulty of strain‐induced martensitic transformation (SIMT) of austenite grain in LDSS. When solution treated at 900–1100 °C, with the increase of temperature, the content of quenched martensite decreases, the amount of austenite which can induce transformation induced plasticity increases, and the rolling performance improve. However, when the temperature is higher than 1200 °C, Cr2N phase precipitates in ferrite, which reduces the plasticity of the material.
