许多合金材料,在电化学加工等工艺过程中,表面都会有一定量的氢原子渗入,从而使构件在应力状态下产生脆性破断,即所谓氢脆现象。特别是高强度钢,由于其本身强度高韧性低,对氢脆比较敏感。为此,必须对航空材料的氢脆现象进行研究。 在研究材料的氢脆性能时,要对各种缺口 Many alloy materials, in the electrochemical processing process, the surface will have a certain amount of hydrogen atoms infiltration, so that the components in the brittle fracture under the stress state, the so-called hydrogen embrittlement phenomenon. Especially high-strength steel, due to its high strength and low toughness, more sensitive to hydrogen embrittlement. To this end, the hydrogen embrittlement of aviation materials must be studied. In studying the hydrogen embrittlement properties of materials, to a variety of gaps
