摘要: 用X-射线结构分析、扫描电镜和透射电镜等方法,研究了在H_2S—H_2O系统中使用的奥氏体不锈钢的破裂机理。结果指出,化学反应所产生的氢是造成破裂的主要原因。薄膜试样直接观察指出,在氢引起马氏体相变之前,氢使位错和层错大量形成。氢减弱铁的结合键是引起一系列变化的根本原因。

Abstract：Fracture mechanism of austenitic stainless steels used in H_2S-H-2O system has been investigated by means of X-ray analysis, scanning electron microscopy and transmission electron microscopy. It is shown that the hydrogen produced by chemical reaction is the main cause of failure. The observation upon the film sample indicates that a lot of dislocations and stacking faults have been formed before the formation of the martensite induced by hydrogen. The "DECOHESION" caused by hydrogen has been regarded to be responsible for aforementioned phenomena in such steels.
