钢板近表面区域发生氢致开裂(Hydrogen Induced Cracking, HIC) 时,可能在钢板表面形成泡状鼓包——氢鼓泡 (Hydrogen Blistering)。因此,氢鼓泡通常属于氢致开裂的范畴。 图1 钢板表面氢鼓泡来自网络 侵删 1.氢致裂纹发生的机理: 氢元素无处不在,由于氢原子尺寸非常小,很容易吸附在金属材料表面,并通过扩散进入材...
2.25Cr-1Mo钢A technique of electrochemical hydrogen charging is adopted to study the behavior of hydrogen-induced cracking of 2.25Cr-1Mo steel.The average hydrogen concentration in 2.25Cr-1Mo steel was determined for the occurence of hydrogen-induced cracking(HIC).In order to investigate the ...

2.5 Hydrogen induced cracking (HIC) Hydrogen Induced Cracking is one category of HAC failure mode in which there is no load on pipeline steel. In this mode of cracking, the hydrogen atoms diffuse to the steel’s structure and cause cracking. One reason of diffusing the hydrogen atoms to the...
Hydrogen-induced cracking (HIC) of two-phase alloy of Ni3Al+NiAl was in situ investigated using a WOL (wedge opening-loading) constant deflection specimen in an optical microscopy and using a notched tensile specimen in scanning electron microscopy (SEM). Results showed that the threshold stress ...
