摘要/Abstract

摘要： 采用氢渗透测试、慢拉伸试验等研究手段,探究EH36钢表面、1/4和1/2厚度处的氢陷阱、氢扩散系数及氢脆敏感性。结果表明,表面及1/4厚度处的显微组织主要为贝氏体,表面处的显微组织较为细小,1/2厚度处主要为铁素体和珠光体。可逆和不可逆氢陷阱密度由表面到1/2厚度处依次降低,氢扩散系数随之依次增大。随充氢电流密度或时间的增加,各厚度处拉伸试样的屈服强度、抗拉强度、伸长率均有不同程度的降低,氢脆敏感性随之增大;拉伸断口形貌由呈韧性断裂特征的韧窝状逐渐向呈脆性断裂特征的河流状花样转变。表面处的氢脆敏感性最小,1/2厚度处的氢脆敏感性最大;在1/2厚度处的拉伸断口观察到了一些氢致裂纹。

Abstract: Hydrogen traps, hydrogen diffusion coefficient and hydrogen embrittlement sensitivity at the surface, quarter and half thickness of EH36 steel were investigated by means of hydrogen penetration test and slow tensile test. The results show that the microstructure of the surface and the quarter thickness is mainly bainite, the microstructure of the surface is relatively fine, and the half thickness is mainly ferrite and pearlite. The density of reversible and irreversible hydrogen traps decreases sequentially from the surface to the half thickness, and the hydrogen diffusion coefficient increases accordingly. As the hydrogen charging current density or time increases, the yield strength, tensile strength, and elongation of tensile specimens at various thicknesses decrease to varying degrees, and the hydrogen embrittlement sensitivity increases accordingly. The tensile fracture morphology gradually transitions from ductile dimples with ductile fracture characteristics to river like patterns with brittle fracture characteristics. The hydrogen embrittlement sensitivity is the smallest at the surface, and the hydrogen embrittlement sensitivity is the highest at the half thickness. Some hydrogen induced cracks are observed on the tensile fracture surface at the half thickness.
