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 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...
متن کاملInvestigation of Wear Mechanism in Quenched and Tempered Medium Carbon-High Chromium Martensitic Steel Using Dry Sand/Rubber Wheel
The aim of the present study was to investigate the effect of quenching and tempering temperatures on the microstructure, mechanical properties and the wear characteristics of medium carbon-high chromium wear resistant steel. In addition, the dominant wear mechanisms were studied. For this purpose, austenitizing and tempering temperatures were selected in the ranges of 900- 1000 °C and 300- 500...
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...
