Resumo

The magnetic properties in an Fe-20Mo-5Ni-0.12C alloy, hot-rolled, solution treated at 1230°C and aged at 610°C for different times were measured. These properties were compared with those of the same alloy previously cold-rolled, solution treated at the same temperature and aged under the same conditions. The results for the same alloy without carbon, obtained by other authors, have also been considered. The alloy presented magnetic hardening during aging, reaching a Hc value of 401 Oe after 240 min. of aging. The precipitation hardening was accompanied by thermomagnetic analysis (TMA) in the range 25–800°C and X-ray diffraction.
