摘要: 采用H-800透射電子顯微鏡及正電子湮沒技術,觀察了CSP工藝熱軋低碳帶鋼軋制過程中位錯形貌,并計算了終軋后軋件的位錯密度。結果表明:隨著軋制過程的進行,累積變形量的增加,位錯密度逐漸提高。CSP工藝比傳統工藝生產的同規格產品位錯密度高約一個數量級。Abstract: The dislocation and morphology dislocation density in the hot strip of low carbon steel after finishing pass produced by CSP were investigated by using H-800 transmission electron microscopy and positron annihilation technology. The experimental results showed that the dislocation density increased with the cumulative reduction increased. The dislocation density after the finishing pass is larger than that of the hot strip produced by the conventional technique.
