| 英文摘要 | The precipitation behavior of different phases in a high-silicon stainless steel (6 wt% Si) during aging at 600-1050 degrees C for 24 h was investigated. The morphology, crystal structure and composition of various precipitates were detailly characterized using optical microscopy, scanning electron microscopy and transmission electron microscopy. Four phases were mainly identified:chi-phase,M6C carbides,sigma phase and a new type offcc-phase. During aging at 600-900 degrees C, the main precipitate was (Cr, Mo and Si)-rich chi-phase which was directly precipitated from gamma matrix. The chi-phase was calibrated as bcc structure with a lattice parameter of 8.90 A. The peak temperature for the precipitation of chi-phase was 800 degrees C, and it was dissolved when aging at temperatures above 1000 degrees C. The sigma-phase was observed only at 700 degrees C and grew next to chi-phase. Above 700 degrees C, a newfcc-phase was found to be precipitated along with chi-phase, with a space group ofFd3cand a lattice parameter of 12.56 A. TheM(6)C carbides started to be precipitated at 700 degrees C in the vicinity of chi-phase. And its amount basically increased with the increasing of temperature. An orientation relationship betweenM(6)C/gamma was found: [100]c//[100]gamma, (001)c//(001)gamma, i.e., the cube-on-cube relationship. |
