研究了机械球磨304不锈钢中马氏体和奥氏体纳米晶混合物的磁性能。在低于50 K的温度下，在含有马氏体作为次要相的研磨样品中观察到矫顽力和剩磁的增强。这种行为归因于在低于Néel温度的温度下马氏体和奥氏体相之间的交换耦合。磁场下冷却的样品的磁滞回线的小位移也被观察到。
The magnetic properties of nanocrystalline mixtures of martensite and austenite in 304 stainless steel prepared by mechanical milling have been studied. Enhancements of the coercive force and remanence were observed at temperatures below 50 K in milled samples containing martensite as the minor phase. This behaviour has been attributed to exchange coupling between the martensite and austenite phases at temperatures below the Néel temperature. Small displacements of the hysteresis loops of samples cooled under magnetic fields were also observed.
