Effect of external stress on the Fe-Cr phase separation in 15-5 PH and Fe-15Cr-5Ni alloys.
نویسندگان
چکیده
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 crystal local orientation has also been observed.

Phase transition of Fe–18Cr–8Ni, Fe–15Cr–15Ni and Fe–15Cr–25Ni alloys during mechanical alloying (MA) and after subsequent annealing as studied. For Fe–18Cr–8Ni and Fe–15Cr–15Ni the resulting structure by MA was a nanostructured single-phase BCC solid solution ( ) which iffers from that predicted from equilibrium phase diagram. Furthermore, the equilibrium structure was not achieved after heat ...

In this research the effects of; increasing the amount of nickel and adding aluminum to create and prolong sulfidation resistance of Fe-Ni-Cr alloys have been investigated. Sulfidation tests were carried out at 1100°C in S/O bearing atmosphere. Prior to the tests, the specimens were annealed in argon at 1250°C for 8 hrs. Weight changes were measured and corroded deposits were analyzed byscannin...

The continuum decomposition of the Fe-Cr alloys from initial phase separation to steady-state coarsening with concentrations varying from 25 at % Cr and 30 at % Cr to 33 at % Cr aged at 750 K was studied by utilizing three-dimensional phase-field simulations. The dynamic stages of separation of nanoscale Cr-enriched α' phase were distinguished by the evolution of the volume fraction, particle n...

The effect of lanthanum implantation on the early stage oxidation of Fe-18wt%Cr5wt%Al and Fe-l8wt%Cr-5wt%Al-Iwt%Hf alloys at 1100 OC has been investigated. I t was found that the reactive element enriched surfaces oxidized almost two times faster initially, and the scale that formed had a higher iron content. An extremely wavy scale/alloy interface developed in the early stage due to the accele...
