摘要：
The SHCCT (simulated heat affected zone continuous cooling transformation) of 9Ni cryogenic steel were investigated. The microstructures observed in simulated heat affected zone (HAZ) continuous cooled specimens are composed of bainite (B) and martensite (M) depending on the cooling rates. The dimension of prior austensite grain, M-A constituent content, M-A dimension, M-A area density increase with increased the time of t8/5.
