To enhance the development and utilization of metal materials,the precise control of physical properties and mechanical performance of metal materials is crucial,wherein the hydrogen plays a particu-larly key role in influencing these aspects.In this paper,the impact and hazards of hydrogen on the per-formance of metal materials were summarized.The methods for determining hydrogen content in metal materials in recent years were introduced,mainly including physicochemical method,tube furnace heating-thermal conductivity/infrared method,inert gas protection pulse furnace heating-thermal conductivity/in-frared method,inert gas protection pulse furnace heating-mass spectrometry method,thermal desorption-mass spectrometry method,etc.The corresponding analysis principles,instrument structures,and techni-cal characteristics were summarized.The review of applicable detection objects,analysis range,detection limits,and other specifications could enable the technicians in relevant fields to have a comprehensive un-derstanding of hydrogen content detection in metal materials.
