预充氢金属疲劳损伤研究进展
A Review of Fatigue Damage in Pre-Charging Hydrogen Metal
摘要
Abstract
Under high-pressure hydrogen environment and fatigue load,metal load-bearing components will experience degradation or even failure in material fatigue performance.There are difficulties in hydrogen safety in conducting in-situ hydrogen fatigue damage research on hydrogen components.Therefore,in recent years,alternative methods have been adopted to study fatigue performance of pre-charged hydrogen metals.This paper briefly outlines the hydrogen damage mechanism,introduces the test method for pre-charged hydrogen metals,summarizes the experimental results of the impact of hydrogen on high-cycle and low-cycle fatigue performance under pre-charged hydrogen conditions,and the current research status of establishing a fatigue life model for pre-charged hydrogen metals and conducting quantitative analysis of metal hydrogen damage.Finally,it discusses several methods for improving the fatigue life of hydrogen components by suppressing the effect of hydrogen on metals by changing the infiltration amount and form of hydrogen in the material.关键词
