Abstract

The phase transformations of homogeneous Fe-N alloys of nitrogen contents from 10 to 26 at. pct were investigated by means of X-ray diffraction analysis upon aging in the temperature range from 373 to 473 K. It was found that precipitation of alpha double prime-Fe16N2 below 443 K does not only occur upon aging of supersaturated alpha (ferrite) and alpha prime (martensite), but also upon transformation of gamma prime-Fe4N1-z and epsilon-Fe2N1-x (
