Segregation and Precipitation in iron-chromium alloys: thermal ageing and irradiation effects

نویسنده

  • Frédéric Soisson
چکیده

We present a brief review of recent advances in the atomistic modeling of segregation and precipitation kinetics in iron-chromium alloys, during thermal ageing and under irradiation. The approach takes into account the real diffusion mechanisms: vacancy and, under irradiation, self-interstitial jumps. Migration barriers are computed with effective pair interactions fitted on ab initio calculations. The simulations show how point defect properties control long term kinetic behaviors. The role of magnetic properties is especially emphasized.

THERMAL ANALYSIS AND KINETICS OF THE PRECIPITATION IN WROUGHT Al-Mg, Al-Mg-ScAND Al-Mg-Sc-Me (Me=Zr, Ti) ALLOYS

Precipitation behaviour of wrought Al-6Mg alloys with ternary scandium and quaternary zirconium and titanium has been studied. Hardness measurements and resistivity studies are employed to assess the precipitation behaviour of scandium doped Al-6Mg alloy without or with quaternary additions of zirconium and titanium. Further, the kinetics of precipitations are studied by differential scanning c...

Pretreatment of Gray Cast Iron for Hard Chromium Electroplating (RESEARCH NOTES)

From the standpoint of processing, hard chromium layer plate may be applied to steels, cast iron, aluminum and nickel base alloys. Cast iron can be plated provided that the surface is capable of conducting the required current and is reasonably free of voids, pits, gross silicate inclusions, and massive segregation. There are many difficulties arising from graphite phase and deposition of hydro...

Effects of the Alloying Elements on the Thermal Expansion Coefficients of Nonmagnetic N&base Alloys and Austenitic Steels

A regression model to predict the thermal expansion coefficient (averaged from room temperature to 538’C) of nonmagnetic nickel-base alloys and austenitic steels was obt,ained. The thermal expansion values used in the regression modelling were ta.kcn from published data bases of commercial alloys. An experimental verification of the model was also conducted on 23 nickel-base laborat,ory heats o...

Effect of external stress on the Fe-Cr phase separation in 15-5 PH and Fe-15Cr-5Ni alloys.

The effect on Fe-Cr phase separation of a uniaxial stress during thermal ageing at 425 °C is investigated on a Fe-15Cr-5Ni steel, a model alloy of commercial 15-5 PH steel. The applied stress is shown to accelerate the ageing kinetics, and influence the morphology of Cr rich domains. A dependence of the phase separation decomposition kinetics on the relative orientations of the load and the cry...

Cr incorporated phase transformation in Y2O3 under ion irradiation

Under irradiation, chemical species can redistribute in ways not expected from equilibrium behavior. In oxide-dispersed ferritic alloys, the phenomenon of irradiation-induced Cr redistribution at the metal/oxide interfaces has drawn recent attention. Here, the thermal and irradiation stability of the FeCr/Y2O3 interface has been systematically studied. Trilayer thin films of 90 nm Fe - 20 at.% ...
