Abstract
Ferritic-austenltic duplex steels demonstrate a complex deformational behavior even in the absence of mechanical loads. Purely thermal cycling in the temperature interval from 20°C to 900°C can cause either accumulation of inelastic strains (thermal ratchetting) or plastic shakedown, depending on microstructure morphology and/or the strength and thermal properties of the constituting phases. In this paper, a study is undertaken on duplex steel containing nitrogen, including experimental and theoretical analyses at microscopic and macroscopic levels. High-precision dilatometry and roughness measurements are accompanied by thorough numerical simulations based on different microstructural models.
