为了探讨结构零部件失效的早期行为,采用恒应变幅和恒应力幅疲劳试验,研究了高强度钢的循环蠕变损伤规律,提出了较佳的抗循环蠕变损伤的热处理工艺和显微织组形态。对正常材料蠕变损伤机制进行了讨论。
In order to investigate the early behavior of failure of structural components, the cyclic creep damage of high strength steel was studied by constant amplitude amplitude and constant stress amplitude fatigue test, and the better heat treatment technology of anti-cyclic creep damage and microstructure Group morphology. The creep damage mechanism of normal materials is discussed.
