中文摘要：介绍汽轮机叶片材料X10CrNiMoV12-2-2韧脆转变温度(FATT50)的测试过程及技术难点，并对实验数据进行了进一步分析和讨论。结果表明，FATT50的测试符合ASTM A 370、GB/T 229-1997标准的要求。随着温度的降低，冲击功急聚下降。
英文摘要：The testing process and technology difficulties of ductile and embrittle transferring temperature of steam turbine blade of X10CrNiMoV12-2-2 were introduced, and the further analysis and discussion on testing data were carried out. The results show that the test date of FATT50 accords with the standard of ASTM A 370 and GB/T 229-1997. The impact power fast decreases with the decrease of temperature.
