一名16岁女孩死于海菲兹动脉瘤夹刀片断裂后的急性蛛网膜下腔出血。夹子由17- 7 PH钢制成，在冶金测试中发现其对晶间腐蚀高度敏感。断裂机制是应力腐蚀，由应力载荷、电解环境和敏感钢的组合引起。
A 16-year-old girl died from an acute subarachnoid hemorrhage following the fracture of a blade of a Heifetz aneurysm clip. The clip was manufactured from 17-7PH steel, which on metallurgical testing was found to be highly sensitive to intergranular corrosion. The fracture mechanism was stress corrosion, brought on by the combination of a stress load, an electrolytic environment, and a susceptible steel.
