INFLUENCE OF MORPHOLOGY AND PHASE CONSTITUTION ON CREEP PROPERTIES OF LOW-CARBON MARTENSITIC STEEL
ABSTRACT
In the recent years, thanks to the combination of high corrosion resistance, good weldability, and plasticity, low-carbon stainless steel has gained wide application in different industrial sectors. In order to optimize the process of manufacture of parts from these types of steel, its stress−strain state should be simulated. In the present work, an equation of state that describes the behavior of the material with account for the influence of the phase composition and morphology of the structure on creep properties has been suggested based on the experimental data for 03Kh13N4M steel. The mixture rule and a model of dispersion-hardened material were used to describe the behavior of multiphase material. The reliability of the selected equations was confirmed by agreement with the experimental data.
