摘要
利用热力学计算软件Thermo-Calc,研究了新型马氏体时效不锈钢0.007C·13Cr-7Ni-4Mo-4Co-2W在800～1200℃固溶温度下基体组织和析出相的变化。通过透射电镜(TEM)、选区电子衍射花样(SADP)和X-射线能谱分析(EDS)法研究了马氏体时效不锈钢固溶态显微组织结构。结果表明,马氏体时效不锈钢高温析出Laves- Fe_2Mo相,固溶温度超过1 050℃,析出相全部溶解。
The changes of matrix structure and precipitates of new maraging stainless steel 0. 007C-13Cr-7Ni-4Mo- 4Co-2W at solid solution temperature 800 - 1 200 ℃ have been studied by using thermodynamic calculation soft ware Thermo-Calc, and the structure of solid solution of mamging stainless steel was investigated by transmission electron microscope （TEM）, selected area diffraction pattern （SADP） and energy dispersive X-ray spectrometer （EDS）. Results showed that the precipitate in maraging stainless steel at high temperature was Laves-Fe2 Mo phase, and all precipitated phases were solved as solid solution temperature was more than 1050 ℃.
