摘　　要：本文对在役运行五年后加氢反应器中的试验试块进行了研究，评定了试块母材2Cr－1Mo钢的回火脆性。同时进行了脱氢处理和脱脆处理试验。试验结果表明：在役运行五年后加氢反应器中的试块母材产生了明显的脆化，试块母材的脆化主要是由回火脆引起的。The test block within the hydogenation reactor after 5-year service exposure is investi gated and the susceptibility to temper embrittement of base metal 2 Cr-1Mo is assessed. In addition, the tests of the hydrogen bakeout and the de-embrittling treatment are performed.The test results reveal that the embrittlement of base metal of test block within hydrogena tion reactor after 5-year service exposure increases markedly,and the embrittlement is caused by high temperature tempering within 5-years at 427 ℃
