Abstract The effect of the magnetic transition of γ austenite phase on γ → e martensitic transformation in Fe Mn binary alloys was investigated to calm a longstanding controversy over whether or not γ → e martensitic transformation is terminated at the Neel temperature of γ phase (TNγ), where the paramagnetic-to-antiferromagnetic transition occurs during cooling. Literature review on both martensite start (Ms) temperature and TNγ, experiments, and thermodynamic calculation clearly revealed that the γ → e martensitic transformation in Fe Mn binary alloys is not terminated at TNγ, but suppressed at temperatures below TNγ due to the high stability of antiferromagnetic γ phase.

奥氏体相的磁性转变对 Fe Mn 二元合金中奥氏体-ε 马氏体转变的影响

摘要 研究了 γ 奥氏体相的磁转变对 Fe Mn 二元合金中 γ → e 马氏体转变的影响，以平息长期存在的关于 γ → e 马氏体转变是否在 γ 相的尼尔温度 (TNγ) 终止的争论。 ，其中顺磁到反铁磁的转变发生在冷却过程中。关于马氏体起始 (Ms) 温度和 TNγ 的文献综述、实验和热力学计算清楚地表明，Fe Mn 二元合金中的 γ → e 马氏体转变不是在 TNγ 处终止，而是在低于 TNγ 的温度下由于其高稳定性而受到抑制。反铁磁γ相。
