峰温越高，奥氏体晶粒越粗大，冷却后形成的马氏体板条束尺寸也越大。
The higher the peak temperature, the coarser the grain size of prior austenite, the larger the martensitic lath bundle after phase transformation.
奥氏体组织分割了马氏体束或马氏体板条，减小了有效晶粒尺寸，阻止裂纹扩展，提高材料的韧性和塑性；
Austenite separates the martensite blocks or laths so that it can reduce the effective grain size and prevent cracks from propagating.
弹坑表面的变形带和相变带是由非常细小马氏体板条组成，其硬度非常高，远远高于装甲钢板的基体和淬火硬度。
The deformed band and transformed band are made up of very fine martensite laths, its hardness is much higher than that of the as-quenched specimen.
