| 초록 | This study was carried out to investigate the effect of W substitution on the precipitation behavior of ${ chi}$ and ${ sigma}$ phases in super duplex stainless steel. The ${ chi}$ phase was precipitated at the interface of ferrite / austenite phases and inside the ferrite phase at the initial stage of aging. With an increase in the aging time, the volume fraction of the ${ chi}$ phase increased, and then decreased with the transformation from the ${ chi}$ phase to the ${ sigma}$ phase. The ${ sigma}$ phase was precipitated later than the ${ chi}$ phase, and the volume fraction of x phase increased with the increase in the aging time. The ferrite phase was decomposed into the new austenite ( ${ gamma}2$ ) and ${ sigma}$ phases by aging treatment. The decomposition of the ferrite phase into the ${ gamma}2$ and ${ sigma}$ phases was retarded by W substitution for Mo. The volume fraction of the ${ chi}$ phase increased and that of the ${ sigma}$ phase decreased due to W substitution. The ${ chi}$ and ${ sigma}$ phases were intermetallic compounds, which had lower nickel concentration, and higher chromium, molybdenum, and tungsten concentrations. The ${ chi}$ phase has higher molybdenum and tungsten concentrations than those of the ${ sigma}$ phase. The amounts of chromium and nickel in the ${ chi}$ and ${ sigma}$ phases did not change, but these phases have higher concentrations of molybdenum and tungsten due to W substitution for Mo. |
