The loading rates causing the changes for the fine grain size microstructure are higher than those for the coarse grain size microstructure. The cleavage fracture stress σf and the notch toughness are related with fracture mode and critical event.
细晶试样发生转变的加载速率高于粗晶试样，解理断裂应力σ_f、缺口韧性与断裂模式和临界事件相关，在延—脆转变断裂模式和扩展控制的临界事件下，解理断裂应力σ_f和缺口韧性较高。

细观解理断裂应力主要由临界裂纹的长度决定。
The local cleavage fracture stress is mainly determined by the length of the critical microcrack.
切口试样测得的解理断裂应力明显高于光滑试样。
The cleavage facture stress of notched specimen is much higher than that of smooth specimen.
曲线半径越小，裂纹长度越大，断裂应力也就越低。
The smaller the curvature and the larger the crack length the smaller will be the fracture stress.
