Title:
耐水素脆化特性評価方法
Document Type and Number:
Japanese Patent JP6693130
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of evaluating the hydrogen embrittlement resistance of any member using, as an index, an allowable range of a use environment of the member.SOLUTION: The evaluation method of a hydrogen embrittlement resistance includes the steps of: (1) performing electrolysis using, as a negative pole, a specimen of a test object and determining a negative pole hydrogen charge condition for a hydrogen invasion amount H; (2) performing electrolysis using, as a negative pole, the specimen of the test object to charge hydrogen, then performing a delayed fracture test, and measuring a limit diffusible hydrogen amount H; and (3) determining the hydrogen embrittlement resistance on the basis of the largeness of a negative pole hydrogen charge condition in which the hydrogen invasion amount His smaller than the limit diffusible hydrogen amount H.SELECTED DRAWING: Figure 3
