补充资料:马氏体
分子式:
CAS号:

性质:钢中相形态之一。碳在α-Fe中的过饱和固溶体。具有体心正方晶体结构。是一种单相的亚稳组织。钢经奥氏体化后,以超过一定的冷却速度,在较低的温度下发生的马氏体转变产物。马氏体一般呈板条状、透镜片状或二者兼有之。具有较高的硬度和强度。板条状马氏体韧性较好,透镜片状马氏体韧性较差。钢的各种组织中马氏体的比容量大。具有铁磁性,电阻率也比较高。钢的各种组织中马氏体的比容最大。具有铁磁性,电阻率也比较高。通常钢中碳含量直高,马氏体硬度越高。但韧性很差,要经过回火热处理后才能用。通过淬火得到马氏体,是对钢进行强化的重要手段。超低碳铁镍合金中,加入适量的钴、钼、钛等合金元素,可制成高强高韧的马氏体时效钢。
