标准摘要
[中文适用范围]： 本文件提供了一种利用预充氢试样的慢应变速率试验来评价高强度钢的抗氢脆（即氢延迟断裂）性能的方法。 通过气相色谱、质谱等热脱附分析来定量分析样品中吸附的氢气量。 本文件包括光滑或有缺口样本的测试方法。 它适用于铁素体基钢。 [外文原描述]： This document provides an evaluation method of the resistance of high-strength steels to hydrogen embrittlement (i.e. hydrogen delayed fracture) using slow strain rate test with hydrogen pre-charged specimens. The amount of hydrogen absorbed in the specimens is analysed quantitatively by thermal desorption analysis such as gas chromatography, mass spectrometry and so on. This document includes testing methods for either smooth or notched specimens. It is applicable to ferritic base steels.
