| Abstract |
In order to avoid the confusion due to inconsistency between thermodynamic calculations(free energy difference between γ and ε, △G γ→ε of γ→ε martensitic transformation for Fe-Mn binary alloys reported by previous workers, the thermodynamic data of Fe-Mn alloys, △G(γ→ε)Fe and △G(γ→ε)Mn, were newly formulated, and the thermodynamic calculations of γ→ε martensitic transformation for the Fe-Mn binary alloys were performed with a regular solution model. The calculation results were well consistent with experimental results in wide range of 15 to 28wt%Mn, and were closely approached to Takaki`s calculation results rather than Murakami`s calculation results. |
