主　　题：相变 Fe-Mn-Si合金 γ(fcc)-ε(hcp) 

摘      要：There are two tpyes of phase transformations in Fe-Mn and Fe-Mn-Si alloys when the temperature is decreased,γ(fcc)→ε(hcp) martensitic transformation(MT) and paramagnetic-antiferromagnetic transition (AMT) of γ *** the thermodynamic point of view,the former usually appears in a slightly higher temperature range than the latter because if is generally accepted that the magnetic tansition has a suppressing effect on the thermally induced ε martensite(Sato et al.,1984.,Bogachev and Zvigintzeva,1976;Murakami et al.,1987:Yang et al.,1992) Gartstein and Robinkin(1979) even thought that the γ-ε transformation should be terminated below Neel temperature(TN) due to the decrease of free energy arising from the AMT of γ ***,some experimental results hae indicated the formation of ε phase below T(Li and Wayman,1994:Fujimori.1966).In the present *** behavor of γ-ε transformation below TN was furtherinvestigated by clectrical resistance measurements.
