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。
The test process and technical difficulties of steam turbine blade material X10CrNiMoV12-2-2 are introduced. The experimental data are further analyzed and discussed. The results show that, FATT50 test in line with ASTM A 370, GB / T 229-1997 standards. As the temperature decreases, the impact energy decreases sharply.
