金属材料在一定的环境(介质、温度等)条件中,在静拉伸应力作用下,取决于时间的断裂过程,称为延迟断裂(或迟后破坏)。延迟断裂又称应力腐蚀断裂、氢脆断裂或静疲劳等。目前这个领域的名称尚未有统一的命名。延迟断裂是一种极为危险的脆性断裂,几乎所有合金在特定的环境中都可能发生延迟断裂,随着工业 Metal materials in a certain environment (medium, temperature, etc.) conditions, under static tensile stress, depends on the time of the fracture process, known as delayed fracture (or delayed fracture). Delayed fracture, also known as stress corrosion cracking, hydrogen embrittlement fracture or static fatigue. The current name of the field has not yet been a unified name. Delayed fracture is a very dangerous brittle fracture, almost all alloys in a particular environment may occur delayed fracture, with the industrial
