The rupture reasons of tube joint weld of the stainless steel pressure meter are analyzed. It is characteristic of stress corrosion cracking and inter granular fracture. 分析了不锈钢压力表管接头焊缝开裂的原因,认为此种开裂具有应力腐蚀开裂、沿晶断裂特征。
By launching a specially designed vessel filled with granular propellants by a high low pressure gun, dynamic grain fracture caused by intergranular compression at low temperature is investigated, and fracture degree along with intergranular stress is also obtained. 该文利用高低压火炮发射火药运载器研究动态条件下低温火药的破碎规律,得到了不同颗粒间应力条件下火药破碎程度关系式。
