| description | The precipitation behavior of different phases in a high-silicon stainless steel (6 wt% Si) during aging at 600–1050 °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:
χ
-phase,
M
6
C carbides,
σ
phase and a new type of
fcc
-phase. During aging at 600–900 °C, the main precipitate was (Cr, Mo and Si)-rich
χ
-phase which was directly precipitated from
γ
matrix. The
χ
-phase was calibrated as bcc structure with a lattice parameter of 8.90 Å. The peak temperature for the precipitation of
χ
-phase was 800 °C, and it was dissolved when aging at temperatures above 1000 °C. The
σ
-phase was observed only at 700 °C and grew next to
χ
-phase. Above 700 °C, a new
fcc
-phase was found to be precipitated along with
χ
-phase, with a space group of
Fd3c
and a lattice parameter of 12.56 Å. The
M
6
C carbides started to be precipitated at 700 °C in the vicinity of
χ
-phase. And its amount basically increased with the increasing of temperature. An orientation relationship between
M

C/
γ
was found: [100]c//[100]
