average effective grain size 平均有效晶粒尺寸
Austenite separates the martensite blocks or laths so that it can reduce the effective grain size and prevent cracks from propagating.
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；
The mechanical property and the grain size of the steel ingot after smithing are ensured without generating a crackle during smithing by using a rational and effective smelting method.
