Different modes of heat treatment of Fe - 18% Cr - 0.7% N alloy leadin
g to the formation of gamma and alpha solid solutions of iron and deco
mposition of the quenched structure on aging are considered. Electron
microscopy is used for studying the alloy structure after different he
at treatment modes. The relation of the gamma and alpha phases in the
structure is studied using X-ray techniques. The properties of the all
oy were judged from Rockwell hardness changes. The results are present
ed in the form of a S-shape diagram.
