n.马丁散铁；马氏体；马丁体
The austenite of the alloys possesses strong ferromagnetism, while martensite showes the characteristics of paramagnetism. 奥氏体具有强的铁磁性，而马氏体表现为顺磁或反铁磁性。
The hard second phase, for example martensite, contributed to the superior fatigue strength and higher threshold value. 较硬的第二相，如马氏体，贡献了出众的疲劳强度和较高的开始值。
