低活化马氏体钢真空扩散焊接工艺

Study on vacuum diffusion welding technology of low activation martensitic steel

  • 摘要: 在不同工艺参数下对低活化马氏体钢进行真空扩散焊接试验,通过比较试样显微组织形态、界面结合率及抗拉强度,探究焊接温度、焊接压力对接头组织演化及力学性能的影响. 结果表明,马氏体组织在扩散焊接过程中发生了奥氏体化现象,且焊接温度越高时,奥氏体化程度越高;在一定范围内,提高焊接温度及焊接压力均可增强原子的自扩散效果,从而提升焊缝接头的力学性能,其中焊接温度1 000 ℃,焊接压力20 MPa,保温时间120 min参数下焊接试样的抗拉强度达到1 013 MPa,焊接面结合状况良好.
    Abstract: Vacuum diffusion welding experiments were carried out for low activation martensitic steel at different parameters, the influence of welding temperature and pressure on microstructure evolution, mechanical properties of welding joints were studied by comparing the microstructure, the interfacial binding rate and the tensile strength of welding joints. The results show that martensitic has transformed to austenite in the diffusion welding process, and the phenomenon is more clearly with the increase of welding temperature. Atomic diffusion effect can be enhanced by improving the welding temperature or pressure in a certain range, as well as the mechanical properties of the welding joint. The tensile strength of welding joint reaches 1 013 MPa at 1 000 ℃ while the welding pressure is 20 MPa and welding time is 120 min, and interface condition is well-bonded.
