Deformation Coordination between Component Phases in Duplex Steel Based on 3D Simulation

doi:10.3901/JME.2020.12.085

Abstract

Abstract: Advanced metal materials with two constituent phases usually take advantage of the characteristics of two phases. However, uncoordinated deformation always exists between two phases due to the differences in the properties of each other, and meanwhile, the stress state and deformation characteristics are more complicated. Based on the representative volume element (RVE), a 3D model is constructed and austenite and ferrite distributed randomly in units via a program. Numerical simulations of different comparative phases are carried out, and the deformation coordination are analyzed. The deformation characteristics of individual phase between two constituent phases are discussed in order to clarify the mechanical response in macro-and micro-scale. The results show that both stress and strain distribution in individual phase are uneven. The equivalent plastic strain shows a Gaussian distribution, while the equivalent stress distributes in the negative skewness. In initial deformation stage, the deformation coordination between the two phases is unsatisfactory. As the deformation increases, the deformation coordination between both phases is improved and gradually tends to be stable. In approximately, a linear relationship is shown between the plastic strain in each individual phase and the macroscopic strain. The ratio of strain increment difference between each individual phase and overall duplex steel shows a phase fraction-dependent constant value. The strain distribution parameter K associated with the phase fraction is introduced, whereby the mixed law of strain based on the generalized phase fraction is established to modify classic strain mixing theory. It can more accurately characterize the correlation of composite materials between the change of component and the macroscopic strain, and provide theoretical support for analyzing the coordinated behavior of phase-to-phase deformation of composite materials.
