在同样晶粒度和硬度，不添加杂质的条件下，马氏体有较低的屈服强度、较高的冲击断裂功以及较低的塑脆转变温度，这些都由于较细的平均碳化物尺寸引起。
For the same grain size and hardness in the unembrittled conditions, martensite has lower yield strength higher Charpy fracture energy and lower FATT due to finer mean carbide size.
M1和M2是马氏体的两种变体，有着不同的取向结构和弹性应变能，使得M1和M2在不同的温度下转变成奥氏体。
M1 and M2 are two different martensite variants with diverse elastic strain energy and lattice distortions, which transformation to austenite at different temperatures.
