摘要: 作者研究了钢中显徽组织、流含量及夹杂物对低合金钢12Cr2AlMoV抗硫化物应力腐蚀开裂(SSCC)性能的影响。结果表明,12Cr2AlMoV钢的抗SSCC的能力随着微显组织的变化而变化。在相同温度下处理的正火回火索氏体加铁素体组织抗SSCC能力比淬火回火的索氏体组织好。特定的硬度规定并不能保证良好的抗SSCC性能,其性能主要取决于显微组织。显微组织和钢中的氢扩散系数D有着较密切的联系。钢中硫含量和夹杂物的增加,可使钢的抗硫性能下降。除硫化锰夹杂外,其它脆性夹杂物也可诱发氢致开裂从而引起SSCC。

Abstract：The sulfide stress corrosion cracking(SSCC) resistance of 12Cr2AlMoV low alloy steels with different microstructure and quantity of inclusions was investigated by means of electrochemical hydrogen permeation technique and constant load SSCC test, etc. Experimental results showed that the resistance of the steel to SSCC increased with increase of tempering temperature. The time to fracture, t_f, for normallzed and tempered steel was longer than that of quenched and tempered one, although the heating temperature were identical, For 12Cr2AlMoV steel, the resistance to SSCC was mainly dependent upon themicrostxucture of the steels. The microstructure was closely related to the diffusion coefficient of hydrogen in the steel. The more quantity of sulfur and inclusion in the steel, the lower the resistance of the steel to SSCC . It was found that besides mangness sulphide, other kinds of inclusion would also cause hydrogen induced eracking(HIC)and SSCC.
