Modelling and characterisation of Mo2C precipitation and cementite dissolution during tempering of Fe-C-Mo martensitic steel
The precipitation and Ostwald ripening behaviour of needle shaped Mo2C particles during the tempering of a ternary Fe –C –Mo martensitic steel have been characterised and modelled, taking account of local equilibrium, the capillarity effect, and the simultaneous enrichment and dissolution of cementite. Particles of Mo2C are represented as paraboloids of revolution, with the tip radius chosen to...
متن کاملModelling and characterisation of V4C3 precipitation and cementite dissolution during tempering of Fe-C-V martensitic steel
The precipitation and Ostwald ripening behaviour of V4C3 (plate shaped) particles during the tempering of a ternary Fe – C –V martensitic steel have been characterised and modelled, taking account of local equilibrium, the capillarity effect, and simultaneous cementite enrichment and dissolution. Particles of V4C3 are represented as parabolic cylinders of revolution, with the tip radius chosen ...
متن کاملAtomistically Informed Extended Gibbs Energy Description for Phase-Field Simulation of Tempering of Martensitic Steel
In this study we propose a unified multi-scale chemo-mechanical description of the BCT (Body-Centered Tetragonal) to BCC (Body-Centered Cubic) order-disorder transition in martensitic steel by adding the mechanical degrees of freedom to the standard CALPHAD (CALculation of PHAse Diagrams) type Gibbs energy description. The model takes into account external strain, the effect of carbon compositi...
متن کاملSulfide Stress Cracking Behavior of a Martensitic Steel Controlled by Tempering Temperature
A medium-carbon Cr-Mo-V martensitic steel was thermally processed by quenching (Q) at 890 °C and tempering (T) at increasing temperatures from 650 °C to 720 °C and the effect of tempering temperature, Tt, on sulfide stress cracking (SSC) behaviors was estimated mainly via double cantilever beam (DCB) and electrochemical hydrogen permeation (EHP) tests and microstructure characterization. The re...
متن کاملPrecipitation behavior in a nitride-strengthened martensitic heat resistant steel during hot deformation
The stress relaxation curves for three different hot deformation processes in the temperature range of 750-1000 °C were studied to develop an understanding of the precipitation behavior in a nitride-strengthened martensitic heat resistant steel (Zhang et al., Mater. Sci. Eng. A, 2015) [1]. This data article provides supporting data and detailed information on how to accurately analysis the stre...
