【摘要】 本文阐述了钢中硼平衡集聚时品界硼浓度变化规律的数量关系,阐明了温度的影响,晶界面积的影响规律,冷却时平衡集聚的速度和《冻结》状态和回火时平衡集聚的《解冻》。硼的行为的这些基本规律的揭示,对硼钢的金属学问题和热处理的研究,是必要的基础工作。更多还原

【Abstract】 This paper deals with the quantitative relationship of the boron concentration change in the grain boundary during the equilibrium segregation of boron in steel. The influence of the grain boundary area on epuilibrium segregation, the speed and "freezing" state of equilibrium segregation during cooling, and "unfreezing" of the equilibrium segregation in tempering are discussed.更多还原
