Crystal Plasticity Modeling of Duplex Steels at High Temperatures

Abstract:

The paper considers physical approach to the description of inelastic deformation of two-phase polycrystalline materials – duplex steels. Such approach is based on the introduction the key mechanisms of inelastic deformation in explicit way. The main mechanism of plastic deformation is slipping of edge dislocations. The structure of duplex steel consists of austenite and ferrite phases. At high temperatures ferrite reveals dynamic recovery (DRV) and austenite ability to undergo dynamic recrystallization (DRX). The way to describe DRV and DRX processes within the multilevel approach of elastoviscoplastic modeling is proposed. Obtained results of numerical experiments of uniaxial compression deformation at different temperatures have good qualitative agreement with experimental data.
