本文阐述了钢中硼平衡集聚时晶界硼浓度变化规律的数量关系,阐明了温度和晶界面积的影响规律,揭示了冷却时平衡集聚的速度和“冻结”状态,及回火时平衡集聚的“解冻”。揭示了硼的行为的某些基本规律。
In this paper, the quantitative relationship between the boron concentration in the grain boundary and the boron concentration in the steel during the equilibrium boron agglomeration is expounded. The influence laws of the temperature and the grain boundary area are clarified. The velocity of the equilibrium agglomeration and the state of “freezing” The “thaw.” Revealed some basic rules of behavior of boron.
