摘要
Abstract
Short-term and long-term high-temperature creep rupture tests were conducted on Incoloy901 superalloy,and the microstructure near the fracture surface of the sample was analyzed using scanning electron microscopy.The results show that during the short-term and long-term high-temperature creep rupture tests,a large amount of granular carbides were dispersed at the grain boundaries of the samples,resulting in strain concentration.As the hot deformation time prolonged,creep cavities were formed along the grain boundaries,further promoted crack propagation and ultimately led to the fracture of the alloy specimens.关键词
