Statics and Kinetics of Phase Transformations In Bcc Fe-Cr

Part of the NATO ASI Series book series (NSSB, volume 319)


The Fe-Cr equilibrium phase diagram exhibits a bcc solid solution (α-Fe-Cr) in a wide concentration range at elevated temperatures. The ?-phase which occurs around 50% Cr decomposes eutectoidally below ≈700 K into Fe-rich and Cr-rich bcc phases. Since the formation of ? is sluggish, a metastable miscibility gap for α-Fe-Cr is observed well above this temperature. Recently, demixing in the Fe-Cr system, which is responsible for the “475°C embrittlement” of ferrite chromium steels has received considerable experimental attention. In the following we present applications of the Monte-Carlo technique in the framework of the three-dimensional Ising model to the problem of phase separation in α-Fe-Cr and compare the simulation results with experimental findings.
