摘要

摘要研究了影响钢解理断裂应力和断裂韧性的因素。提出了一种基于碳化物诱导解理断裂的统计方法，该方法可以估计断裂韧性并研究不同变量对断裂韧性的影响。所作的预测与各种微观结构的实验结果非常吻合。

Statistical model for carbide induced brittle fracture in steel

AbstractFactors affecting the cleavage fracture stress and the fracture toughness K 1C in steel have been examined. A statistical method based on carbide induced cleavage fracture is proposed, by which it is possible to estimate the fracture toughness and study the effect of different variables. The predictions made are in excellent agreement with experimental results for a variety of microstructures.
