谢谢你！你提醒了我去查相关文献，我原来就只是突然有这个问题，没想着去查文献，呵呵！因为我不做这个的。
大致看了看，应该是奥氏体的居里点降低了。
Several characteristics of Fe-Ni-Co alloys differ
from the binary Fe-Ni alloys used in reverse martensite
transformation investigations. Both anstenitic
and martensitic phases are ferromagnetic with high
saturation and Curie temperatures substantially above
room temperature. 12 Conversely, in Fe-Ni alloys
containing about 30 at. pct Ni, ferromagnetic saturation
induction and Curie temperature are considerably
reduced in the austenite phase.
不锈钢是Fe-Cr-Ni，估计和Fe-Ni体系比较接近。
