| 摘 要： | 为研究不同热处理条件下内刻V形槽20#钢圆柱壳体的破裂机理,进行了爆炸加载破片回收试验,并观测其断面金相组织.结果分析表明:破片以韧性断裂为主,不同的原始组织对断裂模式有一定影响;淬火钢强度高,易形成绝热剪切带,利于控制破片形状和大小;裂纹源开始于刻槽根部,从壳体内表面延伸至外表面,引起壳体破裂.

| Abstract: | Through fragments collected from tests under explosive loading and observation of metallographic microstructure of the steel sections,the fracture mechanism of V-notches on the inner surface of 20 steel cylinder is studied.The result showed that the fracture mechanism of the case is mainly ductile fracture;quenched steel with high strength easily forms adiabatic shear band,which is in favor of controlling the shell into fragments of predetermined size and shape;the case fractures with the crack extending from the root of V-notch to the outer surface of the case. |
