Abstract Low temperature embrittlement has been observed for some austen-itic Fe-Mn alloys. The transition temperature of embrittlement raises with theincrease of Mn content, and the fracture model becomes intergranular at the lowtemperatures. The segregation of Mn at grain boundaries has been detected and theextent of it directly relates to the Mn content in the alloys. It is considered thatthis is the reason of the low temperature embrittlement of the alloys. No evidencewas found to prove a fcc-fct transition occurring at about-l00℃ as mentioned byBogachev.

Key words: low temperature embrittlement segregation grain boundary phase transformation
