抄録

The compressive flow stress-strain behavior of duplex stainless steels composed of austenite and ferrite with various volume fractions was studied by static upsetting tests to the extent of large strain in the temperature range of cold working from 30 to 350°C. The flow stress of steels deformed to a large strain at less than 200°C are higher than that estimated by the law of mixtures. This difference is due to prior deformation of the softer austenite phase and its rapid work hardening in this temperature range. This is confirmed by a numerical analysis making use of a rigid-plastic finite element method (FEM). As a result, a flow stress model is proposed and compared with experimental data.
