Abstract
Considered in the article, α’-phase growth and coagulation stages under 500°С thermal aging of Fe–22% Cr binary alloy have been investigated on the atomic scale level, with atom probe tomography being applied. α’-phase appearing precipitates are shown to be separated in space. In addition, after 100-hour thermal aging the nucleation stage evolves into the growth and coagulation stage of α’-phase precipitates, with their number density being decreased simultaneously. Deviation of time dependences from Lifshitz-Slezov theory is revealed in Fe–22% Cr supersaturated solid solution alloy.
