摘　　要：将传统的电解充氢装置加以改进 ,并以改进的充氢装置对 2 1/ 4Cr 1Mo V钢进行氢致开裂试验。通过改变各种充氢参数进行氢致开裂试验 。In this paper, the conventional equipment of electrochemical hydrogen charging is improved. With the improved equipment, the properties resisting to hydrogen induced cracking of 2 1/4Cr 1Mo V steel are studied. A series of electrochemical hydrogen charging tests are dong by changing the factors of electrochemical hydrogen charging. It has been shown that the concertration of hydrogen is the important factor influencing the hydrogen induced cracking of 2 1/4Cr 1Mo V steel.

关 键 词：21/4Cr-1Mo-V钢 氢浓度 氢致开裂
