| Abstract | In order to obtain the deformation grain structure for static recrystallization, an initial grain structure are produced by lattice deformation model; aiming at characteristics of different deformation regions and non-uniform distribution of the stored energy in deformed alloy, a multistate free energy (MSFE) function are proposed by introducing a weight factor for the stored energy and a characteristics state factor for different deformed regions. Based on these, the microstructure evolutions of static recrystallization for deformed Mg alloys are simulated by phase field model. The transformation dynamic curve of recrystallization, Avrami curve, and the regularity for stored energy releasing and distribution of grain size in recrystallization process are systematically analyzed. The dynamic regularity of static recrystallization obtained by simulating is in good accord with the JMAK theory, and the Avrami curve by simulating can be regard as a linear with average slopes 2.45, 2.35, 2.19 and 2.15, respectively. The Avrami time index decreases with the true strain increasing. The stored energy releases faster, and tine lasting time of static recrystallization Process is shorter when the true strain is greater. Based on the established MSFE model, the simulation results here are in good agreement with the other theoretical results and experimental results. |
