Phase separation kinetics in a Fe-Cr-Al alloy
TL;DR: In this article, phase separation in PM 2000-trademark steel has been characterized with the complementary techniques atom probe tomography and thermoelectric power measurements during isothermal aging at 673, 708, and 748 K for times up to 3600 h.
