摘　　要：根据T91的CCT曲线确定了等温退火工艺,对T91母管进行了等温退火试验。结果表明,等温退火后,T91母管符合后续冷加工所要求的力学性能,等温退火工艺适用于加热后的T91母管,等温热处理工艺可以提高生产效率。According to the CCT curve of T91, the isothermal annealing process of T91 tube was determined and the isothermal annealing tests were carried out. The results show that T91 main pipe after the isothermal annealing conform to furnish the required mechanical properties, the subsequent isothermal annealing process is suitable for the heated T91 main pipe and isothermal heat treatment process can improve the production efficiency.
