摘　　要：研究了除氢处理对1Cr15Ni4Mo3N钢锻件疲劳性能的影响。1Cr15Ni4Mo3N钢锻造时可从加热气氛(油炉或天然气炉)中吸入氢,并导致锻件疲劳性能显著降低。结果表明:在淬火之前进行520℃×8h的除氢处理,可使1Cr15Ni4Mo3N钢锻件疲劳性能恢复至正常水平。The effect of dehydrogenation treatment on fatigue property of 1Cr15Ni4Mo3N steel forgings was investigated. 1Cr15Ni4Mo3N steel forgings can absorb hydrogen from the atmosphere of a gas or oil stove , and the fatigue property of 1Cr15Ni4Mo3N steel forgings was deteriorated remarkably. The results showed that the dehydrogenation treatment of 520℃×8h performed before quenching enable the fatigue property of 1Cr15Ni4Mo3N steel forgings recover to normal level.
