摘要: 通過定量金相、掃描電鏡、透射電鏡和X射線小角度散射方法研究KQ450微合金鋼在不同控制軋制條件下,工藝參數對其鐵素體晶粒細化和析出物行為的影響.結果表明:加熱溫度對KQ450微合金鋼晶粒粗化比較敏感;析出相是面心立方結構的NbC,VC和V(CN).析出物的平均尺寸隨冷卻速度的增大而減小.

Abstract: The effect of hot-working parameters on the ferrite grain refinement and Precipitation behavior of KQ450 steel during different controlled rolling have been investigated by means of quantitative metallography, SEM, TEM and X-ray small angle scatter analysis.The results show that heating temperature is susceptible to the ferrite grain size of KQ450 steel; the precipitated phases are NbC, VC and V(CN); With increasing cooling rate the average size of the precipitated phases decrease.
