Abstract

In this study, the influence of hydrogen blending ratio on the hydrogen embrittlement behavior of X42 pipeline steel is explored through a series of mechanical tests and found that the hydrogen embrittlement susceptibility of X42 pipeline steel slightly increases with rising hydrogen blending ratios (5–20 %). It is noteworthy that the crack growth rate of compact tensile specimens shows little variation under different hydrogen blending ratios, so we reasonably inferred that the possible reason for the obvious change in the morphologies of tubular and sheet-shaped specimens after hydrogen-induced failure is due to the shortened duration of the crack initiation process caused by the rising hydrogen blending ratio.

氢掺比对X42管线钢氢脆行为影响的综合分析

本研究通过一系列力学试验探讨了氢掺比对X42管线钢氢脆行为的影响，发现随着氢掺比的增加（5 ~ 20%），X42管线钢的氢脆敏感性略有增加。值得注意的是，在不同掺氢比例下，致密拉伸试样的裂纹扩展速率变化不大，因此我们可以合理地推断，氢致破坏后管状和板状试样形貌发生明显变化的可能原因是掺氢比例的提高缩短了裂纹起裂过程的持续时间。

期刊介绍： Pressure vessel engineering technology is of importance in many branches of industry. This journal publishes the latest research results and related information on all its associated aspects, with particular emphasis on the structural integrity assessment, maintenance and life extension of pressurised process engineering plants. The anticipated coverage of the International Journal of Pressure Vessels and Piping ranges from simple mass-produced pressure vessels to large custom-built vessels and tanks. Pressure vessels technology is a developing field, and contributions on the following topics will therefore be welcome: • Pressure vessel engineering • Structural integrity assessment • Design methods • Codes and standards • Fabrication and welding • Materials properties requirements • Inspection and quality management • Maintenance and life extension • Ageing and environmental effects • Life management Of particular importance are papers covering aspects of significant practical application which could lead to major improvements in economy, reliability and useful life. While most accepted papers represent the results of original applied research, critical reviews of topical interest by world-leading experts will also appear from time to time. International Journal of Pressure Vessels and Piping is indispensable reading for engineering professionals involved in the energy, petrochemicals, process plant, transport, aerospace and related industries; for manufacturers of pressure vessels and ancillary equipment; and for academics pursuing research in these areas.
