Phase transformations in high-purity Fe−Mn alloys

  • Published:
Metal Science and Heat Treatment Aims and scope

Conclusions

  1. 1.

    Increasing the purity of Fe−Mn alloys raises the initial temperature of the γ→ɛ transformation, as the result of which a larger quantity of ɛ martensite is formed. The maximum quantity of ɛ martensite (85%) is formed with quenching from 1100° in the alloy of high purity containing 17% Mn.

  2. 2.

    Heat treatment (different cooling conditions in quenching, cold treatment, tempering) has only a slight effect on the quantity of ɛ phase formed. Most of the ɛ martensite is formed during quenching, and it can be considered that the Fe−Mn alloys investigated are insensitive to heat treatment.
